KS3 Science Revision

There are 2 types of electrical circuits.

 

The first is a series circuit:

 

A series circuit only allows the current to travel one route. It also means that you can not turn off different components at different time.

 

The second is a parallel circuit:

 

A parallel cicuit provides more than one route for the current to travel. The currnet will split between routes, but it will be the same at the end as it was at the start. A parallel circuit allows components to be turned off seperatly.
