A diode having potential difference 0.5 ...

A diode having potential difference `0.5 V` across its junction which does not depend on current, is connected in series with resistance of `20 Omega` across source. If `0.1A` passes through resistance then what is the voltage of the source?

A

1.5 V

B

2.0 V

C

2.5 V

D

5 V

Text Solution

Verified by Experts

The correct Answer is:
C

The voltage of the source = P.D. across the diode + IR
= 0.5 + 0.1 x 20 = 2.5 V
