Electricity Grade 11 and 12: Exam

[@stellahstars5584]

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 🙏

[@kevinmathscience]

So glad it has helped you! I do have Electrodynamics on my website. Please check video description.

8.6 i would have wrote eskom no cap

hey, kevin please make a video on electrodynamics, ASAP🙏🙏

[@kevinmathscience]

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

[@SbahleJafta]

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

[@relebogilesetsoalo7504]

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

[@danxgaming8709]

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

[@MokgethiSelepe]

Yes ,terminal is another word.

[@arekativa8325]

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

[@MohaleKabelo]

8.2 what if I use the term external as my Answer

[@swirl._.3]

what year paper is this

[@malikaalibdat7079]

Isn’t the 4 ohm resistor in series? And the 3 ohm and 4 ohm in parallel? Im so confused

[@alexandermeyer8404]

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)

[@AlakhiweAkhile]

Sir where did you get 0,2

[@alexandermeyer8404]

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
