Question

In the circuit given below, the 60 V source absorbs power. Then the value of the current source is ____________

(a) 10 A

(b) 13 A

(c) 15 A

(d) 18 A

I have been asked this question during an online interview.

The doubt is from Series-Series Connection of Two Port Network topic in section Two-Port Networks of Network Theory

Answer 1

Correct option is (a) 10 A

To explain: Given that, 60 V source is absorbing power, it means that current flow from positive to negative terminal in 60 V source.

Applying KVL, we get, I + I1 = 12 A ……………… (1)

Current source must have the value of less than 12 A to satisfy equation (1).
