Potential Dividers - IB Physics

[@Siu76_______x]

I prefer every HL topic over topic 5

[@cyclonevii_0]

A.5...? 👀

[@vulcan20]

I love circuits, but I hate Magnetism (5.4)

[@wrentay2306]

love the video, i can already imagine an impossible ib question based off of the variable resistor 😭

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!

[@GinaMathew-rw9xe]

Love you the video thank you so much for helping me. 🙏🙏

4:28 How did you get 2.4 for the resistance of the variable resistor I keep getting 1.5

[@1_in_8billion]

THANK YOU SO MUCH!!!

I dont think the animation at 1:43 is actually playing.

[@AndyMasley]

There's not supposed to be an animation there, just showing the shape of the circuits

[@immortalmann3094]

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

[@immortalmann3094]

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.

where did you get 4ohms?

[@thomasbeaudet5756]

Hello, in reference to 2:40, how is "1/Req = 1/4Ω + 1/R = (4Ω+R)/4ΩR" ?

[@AndyMasley]

This is just finding a common denominator

[@thomasbeaudet5756]

@@AndyMasley Apologies, I don't get how finding the common denominator here gives such an answer.

[@tiredgirl3074]

@@carlosminguez1349 because you flip the fraction due to the resistance equation for parallel being 1 over the resistance.

bro, e&m is so hard

[@AndyMasley]

Lowkey hardest unit no lie
