On problem 6A and R1 5 ohms and R2 10 ohms , I calculated the equivalent resistance by product over sum as 3.3 ohms. From this calculation 20V is the approximate voltage. The voltage is the same in a parallel circuit as shown. Did the math for the amps. at each resistor and agrees with your math. I omitted all math operations for simplicity for the comment. Thanks for your excellent valuable videos.
i just started getting into batteries and what it takes to run stuff with it, and your videos have been the MOST helpful of all. Hope Solar power will be in this series and how they run. Thank you sir.
On the first example, I simply combined the two resistances into one using 1/R_tot = 1/R_1 + 1/R_2 -> R_tot = 12/5 Ω then just used V=IR -> I = V/R = 12 / (12/5) = 5 A. I think it's a lot easier to just simply the circuit and then determine the current rather than using Ohm's law 3+ times on each path.
When we finished finding the Ohms, what wattage for the ohm's should we go by? What I mean should we go by the battery watts ( volt × the total amps use )or the device's watts ( volt × device amps ) for the ohm's to handle the heat.
Why do people still give examples with conventional flow, its just isnt used any more and has been proven to be that electrons are negatively charged thus flow from the negative to the positive, how do you think lead acid, nicad, sicad. otherwise we would have to discharge batteries to charge them instead of reversing the flow of electron like we would normally other than that, a helpful video.
Unfortunately that’s still how we’re being taught. I am doing a diploma course in electronics and comms engineering and we’re being instructed to calculate everything in respect to conventional flow. It bothers me so much because in reality electrons flow from negative to positive and it chooses the path of the least resistance so it just doesn’t make sense to me.
Isn't that the same formula that you said we can use for calculating the tension using newton's second law on a flat plane? Thanks! It makes it easier to remember :) Also, will you make a video that explains how to get the internal resistance of a circuit using a VI graph please?
What if you don't know the resistance, but only voltage, for example, replace the parallel resistors in your example with LED's. How would you compute current? I'm trying to understand from another video why, for instance, a red LED with a small forward voltage of, say, 2v draws all the current away from a parallel blue LED with a forward voltage of 4v, with both of them sharing a single resistor on the back end. If they each have their own resistor in parallel along with them, everything is fine. thank you.
What happens to the effective resistance if one wire has a resistor while the other has no resistor in a parallel circuit (that has 2 wires)? Can I still use the formula 1/R = 1/R1 + 1/R2 (well, actually no R2), or do I use R = R1 like in a series? because I got a question asking what will happen to the ammeter reading if one resistor is removed from the parallel circuit(the resistor is removed but the wire is still connected). R = 10 ohm (for both R) V = 10 V I = 2 A (when there are two R) ____(A)___________ | | | (+-) (R) | (the R here was removed) | | | __________________ Will the current increase or decrease after R was removed?
Electrons are Negatively charged, so, they flow toward the positive side - from (-) to (+) - and not the other way around, like you pointed with an arrow - from (+) to (-). It is time to get over that Benjamin Franklin's mistake, and get things PROPERLY organized, already, dang it!

My physics final exam is tomorrow and you came at the right time! i wish you a good day and happiness.
How did you do on it?
Good
How was your physics final exam?
I'm skipping physics classes, you explain things way way better. Thanks a lot. Love
It sounds like justin timberlake just taught me how to measure circuits.
😂
?

Thank God for this person. If it weren't for him I wouldn't be able to do my physics work
😲 you finally made me understand it, I've been through this concept 20 different times this year, thank you for explaining it out very clearly.🎉🎉
Finally! I have been scouring the internet for an easy explanation to findig the partial currents of resistors!
The fact this man only has 7.9 Million subscribers is diabolical he deserves more
You are very helpful Sir your explanation ate very clear thank you so much 🎉
No stupid intro no ads no asking for likes I respect it
Fire Video Thank you
Thanks man this help me with my homework and School thank you

Yup. I used the same trick to solve this one.
I generally have no idea what that meant, but once I do, I'm coming back to this comment 20/07/23
thanks, coudnt figure it out for ages, watched the video, instantly understood, thanks
Hey sir, please when you get back to chemistry do a comparison between the basicity of complicates heterocyclic compounds
Sir! You always amaze me. I wish you all the happiness!
Can someone actually help me understand with my work , I literally am stuck on this and is stressing out :/
What are you stuck on
bro’s brain is immaculate
Powerful presentation
When we finished finding the Ohms, what wattage for the ohm's should we go by? What I mean should we go by the battery watts ( volt × the total amps use )or the device's watts ( volt × device amps ) for the ohm's to handle the heat.
amazing video, thank you!
I got an A on my exam by just watching this video. Thank you!
I would die for this man
Thanks I love ur teaching
God richly bless you Sir
Omg bro thank you much. I was worried about my quiz
Thank you Sir very well explained.
Amazing, your videos are great
you are a god sent!

Thank you! Thank you! Thank you! thank you!
God bless your soul
Please make a electrostatic video
is it okay that the I total is equal to 21.660 and if i add the I 1 and I 2 the answer is 21.67 is it considered correct?
“That is a messed up looking 3” 🤣
I’m gonna need to borrow your math skills to get through my AMT program 😅😳
Ty for clarifying
I calculate the total current this way:
First i figure out the total resistance then i say I=V
R
It also works
Great video!!!
:]

Thanks
In a parallel circuit Rt will be less than the smallest resistor. You don't just add the current together
That’s what I thought too. I thought you added the sum for a series circuit not a parallel.
Maybe the resistance values were less in parallel…
Could you use this to work out how much current you would need?
Thanks 🙏🙏
Hello. how to find r1 but you have r2,r3 ,Vt , It?
please answer this question
What software he uses for making tutorials? Plz answer if you know 🙏🙏
Could make a video on sets please?
Thank you so much
I was following until about 7:40 where It+ 2I2 formula. ..did we ever figure how we got I2 and I'm lost now :(
Im guessing the 3 is 1/2 of the 6amp total and then what did u do after that to get the 2 and 4 so I can work the formula out on my final tmrw please
Could you make a video on memristors
What I want to know is,how to solve for voltage
you went from volts for the first two then to amps on the 3rd confused
what if I is given, not V? ((
You can calculate the equivalent resistence in that case, then total Current (i)
After that using the equation V=IR
Great..Thanks
Sir good day,,, can i ask you a circuit design for 4-20ma input signal,,, i have a 500ohms pot. and 24vdc
supply,,,hoping your kind and consideration
How to solve this
I have 12v battery, And i have I1 and R1 but no I2 and R2?
12v I1=3 R1=12 I2=? R2=?
What happens to the effective resistance if one wire has a resistor while the other has no resistor in a parallel circuit (that has 2 wires)?
Can I still use the formula 1/R = 1/R1 + 1/R2 (well, actually no R2), or do I use R = R1 like in a series?
because I got a question asking what will happen to the ammeter reading if one resistor is removed from the parallel circuit(the resistor is removed but the wire is still connected).
R = 10 ohm (for both R)
V = 10 V
I = 2 A (when there are two R)
____(A)___________
| | |
(+-) (R) | (the R here was removed)
| | |
__________________
Will the current increase or decrease after R was removed?
What app do you use to make your videos
Series and parallel is very same formula ?
Thanks bro
Amazing 😍😍😍
It hepled me tq
There's no Voltage in my circuit 🤷
So confused what happens when you don’t have the supply voltage
There will be no current.
If there's no resistors?
Electrons are Negatively charged, so, they flow toward the positive side - from (-) to (+) - and not the other way around, like you pointed with an arrow - from (+) to (-).
It is time to get over that Benjamin Franklin's mistake, and get things PROPERLY organized, already, dang it!
Can u do video for Fourier series
Just use ohm's law to figure it out, why learn more formulas that you don't need to
Please help me😢 how to
3:28
This is weird doesn’t seem like how we do ohms law in automotive.
why is your name oragnic chemistery when you are teaching physics?
I thought V= R x I not V=I/R
dude wtf I did not understand 7:30 like wtf are you talking about
Shut up and rewatch the video it ain’t that hard he ain’t gonna explain it to u figure it out love😘
ii know some easy ways for same problems
👏👏👏
No
Dustin gorres
huh
wtf... what don't you teach??
Thanks
If there's no resistors?
Thanks
