Question:-
Option (A)
2
Option (B)
1
Option (C)
1/2
Option (D)
0
Correct Option:
A
Question Solution:
20 log Ad/Ac = 80
Ad/Ac = 104
or Ad/104 = Ac
or Ac = 2x104/104 = 2
Question:-
Option (A)
2 mA
Option (B)
4 mA
Option (C)
–4 mA
Option (D)
0 mA
Correct Option:
C
Question Solution:
V0 = –4V
if + I = iL
if = 2 mA
iL = V0/RL = -2mA
So, I = –4 mA
