In a p-n junction diode, the behavior between the p and n ends can be understood by analyzing its resistance characteristics. When the resistance is high, the diode is in its "off" state, functioning as an open circuit or a switch that is not conducting.
In the context of this question, the resistance measurement indicates whether or not current can flow through the diode. A high resistance implies that the diode blocks current flow, akin to an open switch, while low resistance means it allows current, acting like a closed switch.
Thus, when the resistance is high, the p-n junction diode effectively acts as a switch in its "off" position, preventing current from passing through.
Therefore, the correct answer to the question is that the diode acts as a switch when the resistance between the p and n ends is high.
In the given circuit, the equivalent resistance between points A and D is:
Assertion : In a semiconductor diode, the thickness of the depletion layer is not fixed.
Reason (R): Thickness of depletion layer in a semiconductor device depends upon many factors such as biasing of the semiconductor.
