I've been looking at the diagram of the circuit from this time stamp. And I did understand the previous paralel configuration, this series configuration is giving me a hard time...maybe its just the visualization but, i just cant see the series here. At exactly 1:42 the current (in theory) should go directly into R1 due to a short wire, while the R2 should be excluded.
I prefer every HL topic over topic 5
love the video, i can already imagine an impossible ib question based off of the variable resistor 😭
my parents make me do ipho bro
You Saved my Life ,Literally
word
Love you the video thank you so much for helping me. 🙏🙏
best youtube
physics tutor
Thank you so much! As always, your videos are really helpful! I just wanted to check, at 2:08, is it "...to give the light bulb 9V"? Thank you!
THANK YOU SO MUCH!!!
Explains the rheostat as well with numerical problem
Good Job
I dont think the animation at 1:43 is actually playing.
There's not supposed to be an animation there, just showing the shape of the circuits
He ment that there is an error at 1:42
There is a short circuit shown when it shouldnt be because its all in a series

4:28 How did you get 2.4 for the resistance of the variable resistor I keep getting 1.5
bro, e&m is so hard
Lowkey hardest unit no lie
Hello, in reference to 2:40, how is "1/Req = 1/4Ω + 1/R = (4Ω+R)/4ΩR" ?
This is just finding a common denominator
@@AndyMasley Apologies, I don't get how finding the common denominator here gives such an answer.
@@carlosminguez1349 because you flip the fraction due to the resistance equation for parallel being 1 over the resistance.
where did you get 4ohms?
