Question

In the circuit the dependent source __________

(a) supplies 16 W

(b) absorbs 16 W

(c) supplies 32 W

(d) absorbs 32 W

This question was addressed to me in an online interview.

My question is from Basic Concepts topic in section EDC Overview of Electronic Devices & Circuits

Answer 1

Correct choice is (d) absorbs 32 W

To explain I would say: P = VIx = 2Ix  Ix = 2 x 16 or 32 watt (absorb).
