Electronic Devices Question 155
Question: 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 W across source. If 0.1 A passes through resistance then what is the voltage of the source
[DCE 2005]
Options:
A) 1.5 V
B) 2.0 V
C) 2.5 V
D) 5 V
Show Answer
Answer:
Correct Answer: C
Solution:
$ V’=V+IR $ = 0.5 + 0.1 x 20 = 2.5 V
