Which mode/modes of conduction represent the salient characteristics of an ideal diode?

Option:

a. Conductivity with zero resistance in forward-biased mode
b. Infinite resistance in reversed -biased mode
c. No voltage drop due to zero resistivity
d. All of the above

Correct Answer: d. All of the above

Explanation:

It is highly not feasible for any diode to act like an ideal diode because no practical diode resemble to the behaviour of an ideal diode. Basically, ideal diode acts as a short-circuit in forward direction and acts as an open-circuit in reverse direction.

An ideal diode exhibits conductivity with zero resistance in forward direction and infinite resistance in reverse-biased condition without any voltage drop since a short has zero resistance. However, the configuration of an ideal diode closed in forward direction and open in reverse direction can be used as a better bistable switch.
