How to Solve Circuit Problems - A Level Physics

This video explains how to solve circuit problems for A Level Physics.

Just a brief look at some of the most important equations you should use, and why you should label circuit diagrams in different colours as you work through solutions. With these equations and tips, you should be able to answer most if not all problems to do with electric circuits.

Thanks for watching,

Lewis

Great video :) Just a note to anyone who doesn't know R1*R2/R1+R2 is only applicable for two resistors in parallel.

Watching this video for 5 minutes will not make you that amazing at doing any problems regarding circuits

Science shorts: You are yet to achieve a that level of power

I don't know why but I thought I'd google this question... not sure why I didn't come to you first. Stupid me. Very helpful vid - thank you.

[Scoobyclipsdoo]

how would you calculate the current coming off each branch if the resistance wasn't the same at each junction?

[Mahmzo]

Amazing absolutely Amazing!!! Thankssss

[motherboardbroken]

Damn this was so helpful, I don't have unit 2 apparently yet I got to do unit 3 this may..this helped a lot .. thanks bro

[seb]

thank you so much
you are very appreciated

[kenken]

You have been helping me a lot! here's my appreciation gift for u🍬🍫

Why do you not consider internal resistance when using Kirchhoff's 2nd law to work out the PD of the remaining circuit?

[fongchan]

Does it matter if the current is flowing in the opposite direction?

[jamesrobinson]

How do you work out the potential difference or current when one of the cells is reversed?
