MCQ

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 $0.1\, A$ passes through resistance then what is the voltage of the source.....$V$

A
$1.5$
B
$2$
✓
$2.5$
D
$5$

✓

Answer

Correct option: C.

$2.5$

c
$\mathrm{V}^{\prime}=\mathrm{V}+\mathrm{IR}$

$=0.5+0.1 \times 20$

$=2.5 \mathrm{\,V}$
