What is the characteristics of ideal diode and practical diode?

Ideal diodes act as perfect conductor and perfect insulator. Practical diodes cannot act as perfect conductor and perfect insulator. Ideal diode draws no current when reverse biased. Practical diode draws very low current when reverse biased.

What are significant of ideal diode?

The key function of an ideal diode is to control the direction of current-flow. Current passing through a diode can only go in one direction, called the forward direction. Current trying to flow the reverse direction is blocked. They’re like the one-way valve of electronics.

What is the state of an ideal diode?

Detailed Solution. Explanation: Ideal Diode: A diode is said to be an Ideal Diode when it is forward biased and acts as a perfect conductor, with zero voltage across it. When the diode is reversed biased, it acts as a perfect insulator with zero current through it.
