Question

Under forward bias, an ideal p-n junction diode will act as a perfect insulator.

• A. 200
• B. 100

Answer 1

The correct option is B 100

Under the forward biased condition, the ideal diode acts as a perfect conductor with zero resistance whereas, under the reverse biased condition, it acts as a perfect insulator with infinite resistance. In other words, ideal diodes act as a closed circuit or short circuit under forward biased condition and act as an open circuit or open switch under reverse biased condition.
