Question

When the resistance measured between p and n ends of a p-n junction diode is high, it can act as a/an:

• A. resistor
• B. inductor
• C. capacitor
• D. switch

Hint:

A p-n junction diode behaves like a switch when its resistance is high (in the OFF state).

Answer 1

The Correct Option is D

Step 1: The behavior of a p-n junction diode. In a p-n junction diode, when the resistance between the p and n ends is high, it behaves like an open circuit, similar to a switch in the OFF state.

Step 2: Conclusion. Thus, when the resistance is high, the diode behaves as a switch, corresponding to option (D).
