What is an electrical circuit?

• a whole bunch of wires

• a broken path that electric charges can flow

• a circuit board

• a complete, unbroken path through which electric charges flow

When a switch is open...

• the circuit is working and gives energy

• the circuit is broken and charges cannot flow

• the circuit is turning lights on

• I don't know...ask Ms. Cednick
