What is the diode current (A) in the circuit:

Detailed Solution for Semiconductor Diode NAT Level - 1 - Question 5

Diode will be in conducting state, when forward biased voltage is applied to it and in non-conducting state, when reverse biased voltage is applied to it. Now, the two batteries may be replaced by a single battery of 2Vwhich will make the diode reverse biased and diode goes to non-conducting state and hence current is zero

The correct answer is: 0
