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
