Question:-
Option (A)
3 loop equations
Option (B)
4 loop equations
Option (C)
7 loop equations
Option (D)
10 loop equations
Correct Option:
B
Question Solution:
(b-n+1) links associated with fundamental loops. So b-n+1= 10-7+1=4
Question:-
Option (A)
Both A and R are true and R is the correct explanation of A
Option (B)
Both A and R are true but R is not the correct explanation A
Option (C)
A is true but R is false
Option (D)
A is false but R is true
Correct Option:
A
Question Solution:
WE = (q2/2C) =(1/2C) J; rea of unit current impulse = q and q = (1/Î).Î = 1 Coulomb where Î ® 0

Option (A)
10 A
Option (B)
12 A
Option (C)
14 A
Option (D)
16 A
Correct Option:
B
Question Solution:
Using Kirchoff’s law, I + 3I + 4I = 24 + 2 x 3I
\ Vb = 3I
Þ I = 12A

Option (C)
A is true but R is false
Option (D)
A is false but R is true
Correct Option:
C
Question Solution:
In order to avoid infinite voltage and infinite power, an inductor current must not be allowed to jump instantaneously from one value to another as v=L(di/dt)
