Question:
For an ideal diode, in forward and reverse biased condition the resistance is respectively
For an ideal diode, in forward and reverse biased condition the resistance is respectively
Show Hint
Think of an ideal diode as a one-way switch. Closed (Forward) = No Resistance; Open (Reverse) = Infinite Resistance.

- infinite, zero.
- infinite, infinite.
- zero, zero.
- zero, infinite.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
An ideal diode acts as a perfect conductor in forward bias and a perfect insulator in reverse bias.
Step 2: Meaning
Resistance is the opposition to current flow.
Step 3: Analysis
- Forward Bias: The diode allows current to flow freely, so resistance is $0 \Omega$.
- Reverse Bias: The diode blocks all current, so resistance is $\infty \Omega$.
Step 4: Conclusion
The resistances are zero and infinite respectively. Final Answer: (D)
