You are way better than all of my teachers From school to University None of did a better job at simplifying these topic like you. You made me realize that physics/math is easy and fun.

[@voltsmech1]

Man you're whoever you think you are, no youtube tutor comes close not even an inch closer the gap is too wide. See how I understood this equivalent resistance effortlessly. I've never regretted subscribing to your youtube channel and I will make sure my course mates subscribe to your channel as a form of appreciation to the amount of work you put in just to make us understand seemingly complex topics easily. Because almost all my course mates did not understand this topic when the lecturer came to deliver to the class.You'll be the reason why i will graduate with First Class. thanks once again! Gracias

[@RTMoney]

Umm... this was so valuable to me. I'm trying to re-learn the math and long-hand calculations from when I was in school in the 80's! Trying to pass a qualification exam. This video was a blessing to me. I'll try and update you on how well I did. Took this same test several years ago, and was completely lost. I think I'll do much better this time. Thank you.

[@austinlam8145]

for some reason i was never taught to redraw the circuit at all. I just watched this video and another one where you both redraw the circuit and my mind is blown omfg. it makes everything so much easier to understand

[@gravityhealer]

Exactly, I'm like wtf. My prof just told us to simplify the circuit in our head instead of redraw it. I'm like wut?

[@MrDoneboy]

Absolutely NO redraws are necessary!. Find total resistance from right to left, back to the source voltage. Then figure the total current by Ohms law. Now, going from left to right...figure your voltage drops across R1 and R6. Then subtract those voltages from the source voltage. Divide the 15 volts by R2 resistance to get 1.5 amps, which is half of the total current. The other 1.5 amps goes thru the rest of the circuit, or just divide the 15 volts by the total resistance of the three resistors in the far right part of the circuit. Bingo, problem solved people!

This just got me through my AP physics II test with a 92%!!!! God bless you man!

[@successthruknowledge]

You do such a great job explaining multiple ways to solve the same problem! In earlier lectures you showed how to do it by summing the resistors in series on right side and then solving the parallel resistors and now you explained the alternate way to solve to find the current through the middle resistor by using the potential difference between two voltage points on either side of the middle resistor and solving for the current through the middle resistor and then subtracting that current to find the remaining current flowing through the resistors in series on the right side of the circuit! Just what I needed explained clearly!

[@didiroxforever]

In physics class, to combine parallel repressors, we have been using the formula 1/Rt =1/R1 +1/R2, but that doesn't seem to be in your video. I'm still kind of struggling to understand circuits as a whole, and it would be very helpful to me if you could explain that rule/ its relevancy to circuits. The right hand rule also has been confusing me as well. I love your videos, they've helped me loads in AP Chem and in physics. I'm really glad that there are people out there who make videos to help others, rather than click-baited videos.

[@doctorluzbubs258]

1/Rt = [1/R1 + 1/R2] and don't forget it's to the power of -1

[@doctorluzbubs258]

You only combine them when u are trying to figure out the current encompassing the whole device (circuit). Once you do that you can troubleshoot your device with a multimeter and see where its failing you.

[@sea5205]

didiroxforever that method still applies, in the first question he did he said the total resistance for the the two ten ohm resistors in parallel was 5. He got that by adding 1/10 + 1/10 then finding the inverse of that answer

To compute 2 resistor in parallel with different value just multiply the Numerator then add the Denominator and Devide the value that you get in 15:31 minutes 12 * 4 = 48 (Numerator) then 12 + 4 = 16 therefore 48/16 = 3ohms

Got confused about the current you wrote down towards the end. At 28:09 Should the current going from C to E be 1.7295 and not 0.5765 which is the current going from C to D to E?

I believe you had it correct you are just slightly confused. The current from C to E from the top going right and down is 0.5765A (this is the current going through the 12ohm series combination which is the 3 and 9 ohm resistor combination). But the current going the 4 ohm resistor (diagonal section) is 1.7295. I hope this helps!

There is also another way you could solve the current going through the 3 branches @ 28:00 , you could find the equivalent resistance of r1 and r2, then use that equivalent resistance and the current to find the voltage once you have the voltage you could then find the individual current of r1 and r2.

[@magnumopus1415]

Hi sir, i am sure the calculation is wrong at 28:14, the current passing the 4 ohm resistor must be 1.76. It cannot be 0.576 because then the total current won't be 4.615, and so you violate KCL, and we calculated the current across the resistor is 1.76A

Yeah he mixed them up. But switch the current for i1& i2 respectively and you'll get them right
