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.
