Question

Resistance of an ideal p-n junction in forward and reverse bias respectively will be :

• A. infinite and zero
• B. finite and zero
• C. zero and finite
• D. zero and infinite

Hint:

An ideal p-n junction has zero resistance in forward bias and infinite resistance in reverse bias.

Answer 1

The Correct Option is D

Step 1: Ideal p-n Junction Resistance.
In forward bias, the resistance of an ideal p-n junction is zero, as current flows easily. In reverse bias, the resistance is infinite because no current flows.

Step 2: Conclusion.
Hence, the resistance of an ideal p-n junction is zero in forward bias and infinite in reverse bias, making the correct answer .
