Electric charge and current



In the previous electricity videos, we looked at electric charges that don’t move.  These charges are called static charges.  Here, we’ll start to look at charges that do move.

A flow of electric charge is called an electric current – the greater the rate at which electric charge is passing a particular point, the greater the current.  In this video, we’ll explain this idea in more detail, before going on to look at and work through a few examples in the use of the key equation Q = I t.
