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.
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?
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.
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.
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.
So if im right The given is +24V R1 5Ω R2 8Ω R3 12Ω And the instructions are to find the value of current in each load and totoal current in the circuit I1 = V/R1 = 24V/5Ω = 4.8A I2 = V/R2 = 24V/8Ω = 3A I3 = V/R3 = 24V/12Ω = 2A I=I1+I2+I3=4.8A+3A+2A I= 9.8A
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!
Ah yes, the burden of knowledge interfering with the ability to just accept something that is inaccurate and move on. A mistake was made by Benji and we honour him by being like “Whatever you say pal ;)”. Relatable thought, have a great day 😂

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.🎉🎉
You gonna be a good dad one day
No stupid intro no ads no asking for likes I respect it
The fact this man only has 7.9 Million subscribers is diabolical he deserves more
I would die for this man
thanks, coudnt figure it out for ages, watched the video, instantly understood, thanks
Thanks man this help me with my homework and School thank you
amazing video, thank you!
Sir! You always amaze me. I wish you all the happiness!
You are very helpful Sir your explanation ate very clear thank you so much 🎉
Hey sir, please when you get back to chemistry do a comparison between the basicity of complicates heterocyclic compounds
Thanks I love ur teaching
bro’s brain is immaculate
Amazing, your videos are great
Powerful presentation
Thank you Sir very well explained.
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.
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
God richly bless you Sir
Omg bro thank you much. I was worried about my quiz
you are a god sent!
I got an A on my exam by just watching this video. Thank you!
Thank you! Thank you! Thank you! thank you!
Thank you so much!
Thanks 🙏🙏
Can someone actually help me understand with my work , I literally am stuck on this and is stressing out :/
What are you stuck on
Amazing 😍😍😍

God bless your soul
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
Great video!!!
:]
Please make a electrostatic video
8:46 so if the r1 is lower than r2, then r1 is ignored?
What app do you use to make your videos
Great..Thanks
I’m gonna need to borrow your math skills to get through my AMT program 😅😳
Thank you so much
I calculate the total current this way:
First i figure out the total resistance then i say I=V
R
It also works
Could you use this to work out how much current you would need?
It hepled me tq

Could make a video on sets please?
Could you make a video on memristors
Thanks bro
What software he uses for making tutorials? Plz answer if you know 🙏🙏
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?
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
Series and parallel is very same formula ?
Hello. how to find r1 but you have r2,r3 ,Vt , It?
please answer this question
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…
Just use ohm's law to figure it out, why learn more formulas that you don't need to
What I want to know is,how to solve for voltage
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
So if im right
The given is
+24V R1 5Ω R2 8Ω R3 12Ω
And the instructions are to find the value of current in each load and totoal current in the circuit
I1 = V/R1 = 24V/5Ω = 4.8A
I2 = V/R2 = 24V/8Ω = 3A
I3 = V/R3 = 24V/12Ω = 2A
I=I1+I2+I3=4.8A+3A+2A
I= 9.8A
you went from volts for the first two then to amps on the 3rd confused
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?
Can u do video for Fourier series
Find it easier get total resistance then just use ohms law get total current essentially the same result just find formula easier to manage 1/r1+1/r2
If there's no resistors?
why is your name oragnic chemistery when you are teaching physics?
So confused what happens when you don’t have the supply voltage
There will be no current.
There's no Voltage in my circuit 🤷
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=?
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😘
@@mariambazzz3559that’s a bit condescending

This is weird doesn’t seem like how we do ohms law in automotive.
A bit odd that you're using conventional theory and not electron theory.
ii know some easy ways for same problems
takig a shit rn
I thought V= R x I not V=I/R
huh
Dustin gorres
wtf... what don't you teach??
No
Thanks
If there's no resistors?
Thanks
