Modern Physics Ques 222
- The reading of the ammeter for a silicon diode in the given circuit is
(2018 Main)
(a) $13.5 $ $mA$
(b) $0$
(c) $15 $ $mA$
(d) $11.5 $ $mA$
Show Answer
Answer:
Correct Answer: 222.(d)
Solution:
- For silicon diode, potential barrier is $0.7 $ $V$.
Therefore, the given circuit is as shown in figure.
$ I=\frac{\text { net emf }}{\text { net resistance }}=\frac{3-0.7}{200} A=11.5 $ $mA $
