Electrical Power

The rate of energy transfer.


1. Electrical Power

The rate at which energy is transferred in electrical components is the electrical power. Here I show you how to derive P=IV and the other equations that you need to know.


2. Why Work is Equal to ItV

This video explains why electric work is equal to ItV in circuits for A Level Physics.

Energy transferred by components in circuits can be calculated using this simple equation, W=ItV. This video shows how to derive the equation for the work done in an electric circuit.
