A level/IB physics revision - Electricity (part 2 - solving circuit problems) (AQA spec A)

Resistivity, resistors in series and parallel, and how to solve circuit problems. Expand this text to see timestamp links to each section.

This video covers how simplify a complicated circuit to deduce the current and voltage at any place in the circuit, by applying some simple circuit rules.

It's based on the AQA A-level specification, but it's equally suited to IB physics, or any post-16 course.

0:11 Resistivity
1:10 Resistors in series
1:49 Resistors in parallel
2:47 Current and voltage in series circuits
3:31 Current and voltage in parallel circuits
4:40 Techniques for solving circuit problems in series and parallel

Teaching is all about finding that one way to explain something, everyone can understand a concept if explained in the right way for them. I have listened to my own teacher and text book and this way of explaining it was the one that finally did it for me. Thank you

for the first time in forever, i think i understand electricity calculations in physics!

many thanks!

more of these!!!! make a part 3 they really help mate

I can't thank you enough, I now feel I have a greater understanding on circuits :D
