Option (B)
2000 Hz
Option (C)
500 Hz
Option (D)
250 Hz
Correct Option:
B
Question Solution:
BW1=



= 2(1000)=2000 Hz
Question:-
Option (A)
4V
Option (B)
Option (C)
Option (D)
Correct Option:
A
Question:-
Option (A)
0A
Option (B)
2A
Option (C)
4A
Option (D)
-4A
Correct Option:
D
Question Solution:


1-la=3
=> la=-2A
=> 3+lb=5
=> lb=2A
l=la-lb=-2-2=-4A
Question:-
Option (A)
10A,100 A/sec
Option (B)
0, 13.53 A/sec
Option (C)
10A, 8.66 A/sec
Option (D)
0, 36.6 A/sec
Correct Option:
B
Question Solution:
iL(0+)=iL(0-)=0


iL=10 (1-e-10t)

=100 e-10t
