Electric Circuits - Tip 5: calculate total resistance in seconds ( IB and A-level Physics )

Tip 5: Learn how to calculate the equivalent resistance of a circuit in a matter of seconds!

This video is the last 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. https://youtu.be/p-z-o2n61fs

Tip 2: When relevant, think in potentials at a point instead of voltages (voltage = potential difference). https://youtu.be/GVmZ-72Efkw

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

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

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!
