Question

If i1 = 3 cos(4t) and and i2 = 0. Find v2.

(a) -24 sin(4t) V

(b) -36 sin(4t) V

(c) sin(4t) V

(d) -sin(4t) V

I had been asked this question during an online interview.

The origin of the question is Magneticaly coupled circuits topic in division EDC Overview of Electronic Devices & Circuits

Answer 1

Correct answer is (a) -24 sin(4t) V

For explanation I would say: v2 = -3 d(i1)/dt + 2 d(i2)/dt.
