Q122NEET 2000 · AIPMTEasy

P-N Junction Diode

From the following diode circuit, which diode is in forward biased condition

Show answer and solution

Answer: (a)

Forward bias: anode potential $>$ cathode potential.
(a) $0 > -2\text{ V}$ : forward.
(b) $0 < 2\text{ V}$ , (c) $-5\text{ V} < -2\text{ V}$ , (d) $5\text{ V} < 12\text{ V}$ : reverse.
So the answer is (a).
