Electrical Circuit

 
An electrical circuit is a path which electrons from a voltage or current source flow. Electric current flows in a closed path called an electric circuit. The point where those electrons enter an electrical circuit is called the "source" of electrons. The point where the electrons leave an electrical circuit is called the "return" or "earth ground". The exit point is called the "return" because electrons always end up at the source when they complete the path of an electrical circuit. The part of an electrical circuit that is between the electrons' starting point and the point where they return to the source is called an electrical circuit's "load".
 
 
 
 
 
This activity allows pupils to investigate simple circuits by dragging circuit components into place to make a working circuit. The activities form an introduction to practical work exploring circuits. Pupils have the opportunity to experiment with switches to control components in order to find out that a circuit will not work if there is a break in it.
