Question

What happens to the circuit when the switch is off:
(A) The circuit is complete
(B) There is a gap in the circuit.
(C) Electricity flows continuously
(D) Electricity flows discontinuously

Answer 1

We are all familiar with the working of a switch. A switch is a very essential part of any circuit or electrical device. The ultimate control of a device or a circuit is in the switch. There are two modes for the switch, one is when the switch is on and the other is when the switch is off. In both cases, the circuit will be in different states. Here we are asked about the states of the circuit when the switch is off.

Complete step by step solution:
A switch is an electrical component in a circuit that connects or disconnects the path through which the electrical current. A switch can be used to divert the path of current or to interrupt the flow of current. A switch completes the circuit. That means when the switch is on the circuit will be complete and the current will flow through the circuit without any interruptions. Such circuits are called closed circuits. But when the switch is off the circuit is incomplete such a circuit is called an open circuit and current will not flow through the circuit. In an open circuit, there will be a gap in the circuit that hinders the flow of current.

Therefore, the correct answer is Option (B): There is a gap in the circuit

Note:
Switches are electromechanical because they work partly electrical and partly mechanical. There is not just one type of switch. There can be different kinds of configurations for switches. The most common type of switch that we are familiar with is the on/off switch. But knobs, regulators, actuators, etc. can also be considered as a kind of switch.
