Course Description
Capacitors is a topic within Edexcel International A level physics.
In Edexcel International A level physics, the study of capacitors is part of IA2 Unit 4 "Physics on The Move".
Capacitors involve exponential decay equations, so if you like maths, you'll enjoy this topic. The maths skills you need are also taught within the course in case you don't study maths.
