Electric Circuits - Tip 4: Use Kirschhoff Laws ( IB and A-level Physics )

Tip 4: Take advantage of Kirschhoff laws !

This video is the fourth 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 out 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.

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

Tip 3: Prepare the analysis of a circuit by drawing first arrows for potential differences and currents.

Tip 5: Calculate equivalent resistance of two resistors in parallel in seconds!

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.

Exercise 2: for circuits with multiple batteries.

Have fun and good luck!
