Current and Circuits

What is a circuit?

• an outlet or switch

• a path which an electric current flows

• a poor conductor

What is an electric current? 

• the flow of electricity 

• electricity moving in only one direction

• a switch that gives power

What is a switch? 

• part of the toaster that you plug into the wall

• an outlet that gives power

• part of a circuit that starts or stops the electricity

A conductor is ____________

• something that allows electric current to flow easily

• something that limits the flow of electricity

What happens when you flip on the switch for a light?

• The electrical source turns on.

• The circuit closes, and the electric current flows to the light.

• The circuit opens, and electric current flows to the light.

• Electric current is transferred from a different load to the light.
