Thank you Kevin, we all appreciate the videos, matric during covid would have been a terrible nightmare without your videos. Can you please make a video electrodynamics 🙏

Hello, unfortunately, It wont be released until until next term. Sorry for the delay.

quick question sir , what if your were given the R connected in series and not given one of the resistance connected in parallel how do you calculate the resistance of resistance R in parallel

why am I getting a diff value when I use emf - internal voltage when I wanna calculate the v external

For 8.2 can I answer potential difference? Or even external voltage? Btw thank you so much for making these vids it’s truly so helpful and you have helped me achieve things I never thought I could

Yes ,terminal is another word.

Sir why am i getting a different value when i use the Emf=I(R+r) formula for 8.5? I'm now confused

Isn’t the 4 ohm resistor in series? And the 3 ohm and 4 ohm in parallel? Im so confused
@alexandermeyer84046 ай бұрын
4, 3, and 4 are all in parallel, to make it easier, they are only in series if you can draw a line with your pen without picking up the pen to include the resistor. hope that makes sense ---------R-----R---(series) =====R==== (parallel)

Sir where did you get 0,2
@alexandermeyer84046 ай бұрын
0.9v was lost ('decreases' according to description between question 8.1 and 8.2) Amps is 4.5. so: I=(volts lost)/(internal resistance) 4.5 = 0.9/r.. -rearrange the equation by multiplying both sides with 'r' 4.5r = 0.9.. -rearrange the equation by dividing both sides with 4.5 r(internal resistance) = 0.9/4.5 r=0.2
