A student designs and builds the circuit shown in the picture. Which part of the circuit converts electrical energy into another form of energy?

• wire

• switch

• battery

• light bulb

Which statement explains why the light bulb is not lit?

• The battery is dead, so there is no electrical source.

• The switch is open, so electrical cannot flow through the circuit.

• The light bulb requires more electrical energy than the battery can provide.

• The wires are not conductors, so electric current cannot flow through the circuit.
