Grade 8 : Electric Energy and Electric Circuit

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

Will this circuit light the bulbs?

• Yes, both will light up

• Yes, but only the one on the right

• Yes, but only one on the left

• No, neither of the bulbs will light up

Is this a working circuit?

• Yes

• No
