A​ (a)   is a complete electrical path. An ​ (b)   is an electrical path that is not complete.

• closed circuit
• open circuit
• open current
• closed current

What is the purpose of a switch in an electric circuit?

• to change the direction of the current

• to provide a "push" to electrons

• to allow the circuit to be opened or closed

• to increase power to the light bulb

A circuit contains a battery, a wire, a switch, and a bulb. What would happen if you removed the battery?

• The current would not flow.

• The current would flow faster

• The bulb would glow more brightly

• The bulb would glow less brightly
