Martin hooked up the following circuit. He noticed that the light did not turn on. How could he fix the circuit to make it work? Martin needs to have one wire coming from one side of the battery to the light bulb and one wire coming from the other side to the switch. To make a closed circuit, he can use a wire to connect the switch to the light bulb.

Martin needs to connect one wire from the switch to the battery and one wire from the battery to the light bulb. When he does this, it will be a closed circuit that allows electricity to flow.

Martin needs to turn the battery around. When he does this, it will become a closed circuit allowing electricity to flow through the circuit in a loop.

The switch is in the open position. If Martin lifts the switch, it will close the circuit and electricity will flow from the battery to the light bulb in a loop.
