Answer 2

Explanation:

The bulb glows only when electricity is passed through it .

The electrons are passed through the wires.When the switch is off , it prevents the flow of current , so the bulb does not glow . But when the switch is on , it completes the circuit . Thus , the bulb glows when the switch is on.
