The Engineering Mindset if I break one bulb in the parallel circuit does the A reading for the other bulb go back to full flow? Or is it still split in half even tho the electrons are no longer flowing through the other circuit. In other words would one bulb get brighter the moment you broke the other or would it stay the same brightness. Probably a dumb question but this is a new found interest of mine thanks to you. You do a great job of explaining now I just need to commit all of these formulas to memory. Thanks a ton for the videos
0.5A+0.8A=1.2A...
Are you sure the calculation at 3:24 is correct?

Correction at 8:12.
0.8 amps + 0.5 amps = 1.3 amps. 😉
You're correct, well spotted.
whoops
Was shouting at the telly there for a minute
Wow
lol I instantly paused the vid to search for this comment.
I got a wireman exam coming up nowhere online gives u the refreshing of basic electrical work like you do thank you for these videos god bless you 🙏🏻🙏🏻🙏🏻
How'd you do on the exam?
@@grindstone007 he got 0
Answer:
1.) 1.0169
2.) 0.4 A
1.5 A
4 ohms
Your channel is a gift to humanity.
May we cherish it.
you're under his genjutsu
As someone who struggles to learn things "just because", I really appreciate your explanation of why we calculate total resistance in a parallel circuit that way. Will definitely help make it stick now I can actually rationalise it. Thank you 👍
Holy crap, that conductance bit made it make so much more sense. Thanks a lot.
Up until a few weeks ago my electrical understanding extended to being able to wire a plug. With your series of excellent videos you have expanded my understanding in this area. Thank you very much for sharing your knowledge.
Thank you for these videos. A few weeks ago I knew NOTHING and just wanted to learn some basic circuitry for low voltage DIY projects for gardening, automation, etc. You helped me grasp all of this and realize electronics aren’t just “magic”. Thanks again! :)
god, I love the way you explain things... sometimes I watch videos from different sources and got more confused than before the watch. It is apparent that you put the work into explaining things in the clearest way possible. Thanks :)
Your videos are helping me get an intuition for electricity and electronics and I really needed this since I started a job in embedded development and I really wanted to be able to understand the PCB designs and why certain things are done the way they are. Amazing content, I have subscribed and am binging like crazy!
I really found this video very helpful. I have been through so many videos but this really helps to know much more easier for Series connection and Parallel Connection, and their advantages and disadvantages.
I have fixed spots lights in series connection and the first light is very bright and the rest are dull and flickering.
Then I have been through this video and connected spot lights in parallel connection. Now it's really cool.
I must really thank you, you made my day easy. All the best :)
What an amazing explanation of the parallel circuit. Wish someone would have taught like this in school. Great job
How can someone possibly dislike this video?? Thank you for such a well detailed video. I have exams in 2 months
So helpful. I have a whole bunch of tests coming up and this is saving my grades. Thank you :D
This is exactly what I was searching for, a nice explanation and representation and with clear examples :D
SIR THANK U VERY MUCH FOR GIVING ME THESE ELECTRICAL VEDIOS..
Iam a mechanical engineering student but Very weak in electrical engineering..
Now I'm using ur channel to improve my knowledge and its awesome..
Ur teaching is just extraordinary with beautiful animations and examples for beginners.
Thank u very much sir
Thank you for this video, And also I've learnt so much from this channel...
I've seen the comments about your mistakes in this video... I want to say, We all are imperfect and make lots of mistakes and learn from that....
Ans no.1). The total resistance of the circuit is 1.01 ohm
Ans no.2). Current on R2 is 0.4 Amp
Current on R3 is 1.5 Amp
Resistance on R3 is 4 Ohm
Paul: At 3.22 the amp meter shows 3A. Although the math is correct. This error
was put into the graphic to see if we are (paying attention) learning anything.
I came here looking for this. I dont know how he got the numbers for the formula either. I suppose the formula itself is important. I got that the voltage is 36
@@andrewangerer1399 I got confused at this part too. He does write in the video description this was an error and that the multimeter should read "2A" not "3A"
I'm still confused as to why the resistance is 3 ohms

man, you explain this things alot better than how they were explaining me in school, its alot easier to understand electricity with these video, you re doing a great job
Best engineering learning site, with well explained topics and proper diagrams . 💯
Glad to find the channel👮🏻♂️
That BUT, at 12:02 was the missing link in my understanding of electricity understanding. Brilliant, thank you!
This is the best video I have seen on electricity, Thanks, Paul.
Lmao i just spent 20 minutes trying to quantify how 0.8 + 0.5 = 1.2 amps.... then i looked at the comments. 🙃
I also spent too much time questioning my sanity
0.8+0.5=1.3
I just realized my love for this channel
Thank you for explaining where the ones come from! Things like that help me out immensely!
8:05 total current is 1.3A 😊
Resistor 1 and resistor 2 is the sum of 0.8A + 0.5A = 1.3A
Check out NEW resistor video, everything covered! ➡️ th-cam.com/video/DYcLFHgVCn0/w-d-xo.html
3:05 Your example is 2 Amps, but the meter is showing 3A. This may confuse some. I apologize if I'm not the first to point this out, but with 318 comments, I wasn't going to read through them all.
Thank you, I was wondering about that!
Also worth noting that this example provides a figure for total resistance before the video has explained how this figure is derived, which is a little confusing on first viewing. Excellent series though, thanks!
wow, the explanation for parallel resistance and all of the divisions NOW totally makes sense! thx !!!
and here's my 5 cents:
a good (and quite extreme) example would be to make a short circuit in parallel, thus (despite the other resistors) the current would flow via the easiest path.
It's easier to see it as "leakage". the smaller the resistance - the bigger the hole is.
therefore, the more "joints" = the more holes you have with current leaking through.
therefore, in parallel setup - the total resistance would ALWAYS be smaller, than the weakest part.
12:20
Never knew about electronics but this series has sparked my interest.
Great video but at 8:10, total Current of 0.8+0.5=1.3A! Not 1.2! ;-)
You're correct, well spotted.
Beautiful explaination for Basics
the video is very helpful for me. thank you very much.
KCL Kirchhoff's current law. Wonderful explanation. Paul: A little too fast on the
excellent graphic and voice over. Perhaps trying to squeeze everything into
the 16 minutes.
I’d love to see your take on Kirchhoffs laws, and nodal analysis.
I'll add them to the list
All my questions about WHY that i found no answer are solved in your channel. Visual examples + WHY explanations are top quality content, you make people learn for real
Glad to help!
Thank you so much sir. This video helped me a lot. God bless you 🙏
your videos have changed my life. all kinds of projects and homowner diy cost savings are attributed to these videos.
also, per my research @7:29 connecting batteries in series does not increase amps, but volts instead.
I'm running for an opportunity in my job as a process technician and I came here to review. I understood better in English than in my native language (Portuguese) hahaha thanks a lot !
studying for a med entrance exam after several years of not studying physics. Your videos have been the most helpful so far for electricity. Thank you so much, I'm very grateful !
How did it go?
@@linkdude600yeah
ps, Really appreciate the work you have put into these videos !!!
Excellent. I wish I ve the gold medal to gift u......
It had help me tremendously, Thanks
Your every video is a masterpiece.
These videos are incredible!
Wonderful explanation of total resistance of parallel resistors.

thank you for doing this video. It's help me a lot in my final exam lol!
Thank You For this explaination
Thanks for sharing it with us
I have a degree in mechanical engineering. Was never terribly interested in the electrical side of things because it was harder for me to grasp, so I never paid much mind to my electrical classes. Not to mention I had a very quiet professor from I think the Shandong region of China with a thick accent.
She was a perfectly nice and pleasant person but when you can barely hear or understand the lecture in a big lecture hall you become even more disinterested than you already were.
Fast forward to today and a large part of my job is troubleshooting and resolving electrical issues in an industrial environment. Finally having hands on experience and excellent one-on-one instruction from my boss (an electrical engineer) has *sparked* an interest in electrical systems and hobby circuitry.
So here i am, refreshing myself to fill the gaps in my knowledge. I can wire up a 3-phase motor complete with relays wired into a PLC, but I couldn't remember the basic principles behind current in series vs parallel circuits.
And it turns out mechanical systems are quite lovely when you know how to electrically automate them.
See our new video on how to build mechanical versions of electronic circuits? Watch here: th-cam.com/video/Zv9Q7ih48Uc/w-d-xo.html
Lovely animations, and I liked that there was a mistake in the calculations, made me feel more confident, and know how to stick to my guns.
awesome. Just awesome. You should make an online course for electronics. I would buy it. Also...the soldering kit on amazon is not available. Recommend another
Excellent content!
Question 1:
Rt = 1.020 Ohm
Question 2:
I2 = 0.4A
I3 = 1.5 A
R3 = 4 Ohm
I got 1.017 Ohm (60/59), it could be rounded to 1.02, but the extra zero after the 2 I believe is a precision error. I may be wrong tho
@@buddablackmusic Calculate the total resistance first, then use that total resistance to check if your values are correct
Hey brother , can you please make some stuffs for Mechanical Engineering as well.
It would be a very great of you man.
By the way You just won my heart through these types' of videos
Wish you could make some vids on M.E. too.
Thanks learned so much
Thanks for that lecture
This explanation was best
thnx and big respect from Montenegro MNE
Im in love with this channel ❤️ 🌩 ⚡️
THANK YOU! YOU FREAKING SAVED ME
Thank u bro my brain is fully advance now 💯👍❤️
Very helpful
Thank-you sir
Bro... i used to learn electrical engineering... my instruct sucks.. I quit because it was so boring.. im enjoying your teaching instead... I've learned something for sure!
Thanks for sending this video out today bruv! Keep em coming - IBEW!
Plz make one vedio on 'Shunt' in DC circuit,very informative vedio.
Well done sir
youve done more to teach me than my teachers have
Great ❤
gracias mi rey se me aclararon varias dudas de el como funciona la electricidad, incluso sobre la importancia de los circuitos en serie (en mi carrera no los entendí, ni mucho menos su importancia y aplicación)
I learned both directions of current flow. After 50 years of working in electronics as a broadcast engineer, I came to the conclusion that theoretical direction of electrons doesn't matter. It only mattered in school. In the field, I have never needed to ascertain which direction. It only matters that they are flowing, by how much, or not.
Thank you
Thank you sir
Good Video, become a Great Video show the Electron in Wave Form ~, like a Sine~Wave this is how Energy Flows...
Loving home learning :)
0.8Amp+0.5Amps=1.3Amps. You are welcome. BTW Your videos are best to the point videos on TH-cam.
Paul is an absolutely fking Chad he explained the whole lesson is a few minutes better than my physics teacher could ever in his life
Applied to my local college the other day to get on their electricians course, i hope you're still gunna be uploading for the next few years aha
Best of luck! yes, hopefully so
So, how is your electricians course going?
Interesting at 6.42 To reach the Total Current draw we need to FIRST calculate each branch and then add the total of the branches.
13:43 There exists one more (third) formula to calculate power consumption: I^2 x R.
I don't know why is it skipped in the video. Beside that, very good video!
It's skipped probably because it's a combination of 2 formulas V^2*R and V=RI, but im not sure
i) Total resistance Rt=1.020ohms
ii) current through 15 ohms is 0.4 Ampere and R3 is 30 ohms and current through 30 ohms is 0.2 ohm
.Thank you so much sir for giving excellent information and excellence explanation
No the R3 current is 1,5 amps and the R3 ressistance is 3 ohm, to get the current of R3 you just need to:
I(3) = I(t) - [I(1)+I(2)]
I(3) = 2,5A-[0,6A+0,4A]
I(3) =2,5A-1A
I(3) =1,5A
For R3 ressistance you just use ohms law, which states that ressistance is Voltage divided by current, in this case the current we use to get the R3 ressistance is the R3 current, so:
R3=V÷I(3)
R3=6V÷1,5A
R3=3 ohm
Hope it helps
@@AverageTPSenjoyer Your way of calcylating is right, but 6V / 1.5A equals 4Ω, not 3Ω,
@@trapiz9356 Thanks for pointing it out, I think the rest is right
"Watts up"
:D
Waaaaatttttttssss up
Whaazaaaaaaaaaaaaaaaaaaaa
Samarth Srivastava this guy gets it.
I gotta ask, do you know any Canadians? This is literally the next module (the one we're doing tomorrow!) in my electrical course. I've watched a lot of your previous videos but I find it funny on the timing for this. Anyway, I shot you $10/CAD on Paypal so hopefully that's enough to buy yourself a coffee. Thanks for making this series! I'm a very visual learner & I haven't found any electrical series on TH-cam that can hold a candle to yours!
Thanks for your support, Brian. Really much appreciated. Very glad to be helping your studies and great to hear you enjoy the topics.
WOAHHHHH!!! YOU JUST HELPED ME UNDERSTAND JUMPING CAR BATTERIES
NEVER MIND I'M STILL CONFUSED, BUT LESS SO
NOPE I GOT IT, THE DEAD BATTERY SUCKS JUICE LIKE A SLURPY STRAW
I GOT CONFUSED CUS BOTH BATTERIES CONNECT THE POSITIVE TOGETHER
BAD NEWS BOSS, THE REST OF THIS VIDEO REALLY LOST ME, I'LL REWATTCH IT LATER WHEN I'VE HAD MORE COFFEE
Thanks!
Thank you, Ders
Please post zener diode working as well. Thanks
First nice vid finally more electronics
Fast, well done
great
Gonna use this to study for my Electrical ASE A6 exam.
I've been working through your whole series, it's extremely good! One thing that still scares me is not being able to understand how to stay safe when working with electricity. What are the factors I need to understand in order to predict what is safe or not? Is there some Voltage + Amp threshold below which no shock will occur? I want to understand how to know when it's safe.
Thanks
Thank you, Zool!
Great vid. Wouldve been even better if capped off w a practical application. Like making a battery eliminator for 2 calculators or something of that nature. Liked how it started off w the lights. Havent studied in like 10 yrs. Needless to say im pretty rusty.
Computer power section or TV power section will benefit from giving a video on how to operate the voltage and current in the LCD, LED TV's power section.
nice video^^~
Thank you
See you again, friend^^
hello there, I was just wondering. At around 3.40 you ask the question what is the voltage drop. The answer is 12 volts the same as the intial output of the battery(12 volts) ,so there is no voltage drop? . thanks in advance
Hey, at 3:42 if you knew only voltage (12V) you determine resistance by looking at the lamps description and the calculating the current right?
1)0.90 OHM 2)R2=0.4A R31.5 A and 4 ohm
Sir, Small correction at 8:10 .Total current i1+i2 = 0.8A+0.5A =1.3A
This one had me absolutely stumped! Thought I was going crazy
Hey Paul!
Great video. I love the way you explain, but it was too fast. Don’t worry, you did great job anyways.
