Step-by-step solution

The induced electromotive force (e.m.f.) in an inductor is given by Faraday's law of electromagnetic induction, which incorporates Lenz's law: e = -L dI dt Here, e is the induced e.m.f., L is the self-inductance of the coil, and dI dt is the rate of change of current. Comparing this equation with the standard equation of a straight line passing through the origin, y = mx : We have y = e and x = dI dt . The slope of the line is m = -L . Since the self-inductance L is a positive constant, the slope m is negative. The
