Energy, Electricity and Physical Properties

The picture shown is an example of a ______________ circuit because if one bulb burns out, all of the other bulbs will burn out.

• parallel

• series

• open

• battery

The picture shown is an example of a ______________ circuit because if one bulb burns out, all of the other bulbs will stay lit.

• parallel

• series

• open

• battery

Why do the bulbs in a parallel circuit stay lit if one bulb burns out?

• In a parallel circuit, there are multiple paths for the electrical energy to travel.

• The bulbs will not stay lit, they will all burn out.

• The bulbs stay lit because there are many batteries in the circuit.

• In a parallel circuit, the energy travels through the burnt out bulb.
