Question

In the circuit shown below, the voltage V will be __________

(a) – 3V

(b) Zero

(c) 3 V

(d) 5 V

I had been asked this question in class test.

The doubt is from Advanced Problems on Network Theory in chapter Network Theory and Complex Circuit Diagram of Network Theory

Answer 1

Correct option is (a) – 3V

The explanation: By applying KVL, I = 1 A

VAB – 2 × 1 + 5 = 0

Or, VAB = -3 V.
