Electric Circuits - Tip 2: potentials ( IB and A-level Physics )

Tip 2: When relevant, think in potentials at a point instead of voltages (voltage = potential difference).

This video is the second of a series of 5 tips that will help you understand electric circuits. It is aimed at IB Physics, A-level physics and AP Physics students.

Check the other tips for a more complete picture :

Tip 1: Consider charges circulating in a circuit as carriers of energy. Getting grips with this concept will allow you to have a more intuitive approach in solving circuit problems. https://youtu.be/p-z-o2n61fs

Tip 3: Analyse the circuit first by drawing arrows for potential differences and currents. https://youtu.be/_M8HIeArqR4

Tip 4: Take advantage of Kirschhoff laws. https://youtu.be/EERWWUlAwoE

Tip 5: Calculate equivalent resistance of two resistors in parallel in seconds! https://youtu.be/WD5u-wrwBpY

I am also uploading some exam preparation exercises that will give you a very practical methodology to solve circuits with a minimum of effort!

Exercise 1: for circuits with a single battery. https://youtu.be/H0gyq3284x4

Exercise 2: for circuits with multiple batteries. https://youtu.be/CpYryUtMdcw

Have fun and good luck!
