Question

How does a light switch control a light?

a. The switch activates or deactivates the conductors.
b. The switch turns the load on or off.
c. The switch opens or closes the circuit.
d. The switch turns the power source on or off.

Answer 1

c. The switch opens or closes the circuit.

A light switch controls a light by interrupting or completing the circuit that the electricity is flowing through. When the switch is turned on, it completes the circuit and allows electricity to flow through the wires, which in turn illuminates the light bulb. When the switch is turned off, it opens the circuit, and the flow of electricity is interrupted, which turns off the light.
