• Bell 2 only

• Bells 2 and 3 only

• Bells 1 and 4 only

• Bells 1, 2, 3, and 4

When the wires of this circuit are touched to this coin, the light bulb is lit. Why does this happen?

• the coin is an insulator of electricity

• the battery gives the energy to the coin

• the coin is a conductor of electricity

• the light bulb is a conductor of electricity
