A diode having potential difference 0.5 A across its junction which does not depend on current, is connected in series with resistance of 20 Ω across source. If 0.1 A passes through resistance, then what is the voltage of the source?
1.5 V
2.0 V
2.5 V
5 V
Voltage of the source, V′=VD+iR=0.5+0.1×20=2.5V
