What is the primary function of an electric switch in a circuit?
Options
Option A
To increase the current flowing through the circuit
Option B
To convert electrical energy into light energy
Option C is correct
To make or break the circuit
Option D
To store electric charge for later use
Explanation
An electric switch is a simple device used to either allow the flow of current (make the circuit) or stop the flow of current (break the circuit). It acts as a control device to turn appliances ON or OFF. Increasing current is usually done by changing voltage or resistance, converting energy is the function of the appliance itself (like a bulb), and storing charge is the function of a capacitor or battery.
