Modern Physics 6 Question 15

17. The reading of the ammeter for a silicon diode in the given circuit is

(2018 Main)

(a) 13.5mA

(b) 0

(c) 15mA

(d) 11.5mA

Show Answer

Solution:

  1. For silicon diode, potential barrier is 0.7V. Therefore, the given circuit is as shown in figure.

I= net emf  net resistance =30.7200A=11.5mA
