Question

The magnitude of current I indicated in the following circuit is
(A) 2A
(B) 3A
(C)zero
(D) 4A​

Answer 1

Answer:

(c) 0 A

Explanation:

Take junctions as P,Q and R and apply Kirchhoff's junction rule at all the three junctions.

Kirchhoff's junction rule says that the sum of total current leaving to the junction is equal to the sum of total current entering to the junction.

After applying junction rule, we get that the current I should be zero.
