Question

A switch is an electrical device that ______.

• A. only makes the circuit
• B. makes or breaks the circuit
• C. only breaks the circuit
• D. increases the current in the circuit

Answer 1

The correct option is B makes or breaks the circuit

A switch prevents or allows the current to flow through a circuit. When the switch is in the ON position, the current can flow through the circuit. However, if the switch is in the OFF position, current does not flow through the circuit.
Hence, the switch can make or break the circuit.
