IB and A-Level Physics - electric circuits with 2 cells - Exam preparation

You are an IB physics or A-level physics student and you are having trouble with electric circuit exercises, especially those with multiple batteries? Look no more! This video shows you how to find the currents in such circuits using the loop law (second law of Kirschhoff): the loop law allows to define a system of simultaneous equations, the solutions of which are the currents flowing through the circuit.

While I go with you through the circuit, I share many practical tips to make your life easier when you are confronted with electric circuit problems.

You can find tons of free resources that will help you with your studies of high school physics by visiting the website: https://www.physics-made-easy.com/

When there is only one battery, some shortcuts are possible: Check this other video (https://youtu.be/H0gyq3284x4) for circuits which contain only one battery cells.

Best of luck with your studies!
