In the circuit shown if current for the diode is `20 muA`, the potential difference across the diode is

A

2 V

B

4.5V

C

4 V

D

2.5 V

Text Solution

Verified by Experts

The correct Answer is:
C
Since the diode is reversed biased, only drift current exists in circuit which is `20 mu A`
Potential drop across `15 Omega` resistor`=15 Omega xx 20 muA = 300 mu V = 0.0003 V`
Potential difference across the diode = 4 -0.0003 = 3.99 = 4V.
