Assertion (A): Digital circuits are often called switching circuits.Re...
Digital circuits are often called switching circuits, because the voltages in a digital circuit are assumed to be switching from one value to another instantaneously, that is, the transition time is assumed to be zero.
Reason is also a correct statement because digital circuit is a logic circuit, because each type of digital circuit obeys a certain set of logic rules. Hence, both assertion and reason are true but reason is not the correct explanation of assertion.

Digital circuits and Switching circuits
Explanation:
Digital circuits are electronic circuits that operate on digital signals or binary signals which have only two possible values, 0 and 1. These circuits use logic gates to perform logical operations such as AND, OR, NOT, and XOR. Digital circuits are also called switching circuits as they switch between the two possible states of 0 and 1.
Reason for Digital circuits being called Switching circuits
Each type of digital circuit obeys a certain set of logic rules, and these rules govern how the circuit switches between the two states of 0 and 1. The logic rules are implemented using logic gates, and the output of one gate becomes the input of another gate, thus creating a chain of switching operations. The switching action is typically performed by transistors, which act as electronic switches, and these transistors are arranged in specific configurations to implement the desired logic function.
Conclusion:
Hence, both Assertion (A) and Reason (R) are true, but the Reason (R) is not the correct explanation of Assertion (A). The correct explanation is that digital circuits switch between the two states of 0 and 1 using a set of logic rules implemented using logic gates.
