Self-Inductance & Energy

The current flowing through an inductor of self-inductance L is continuously increasing at constant rate. The variation of induced e.m.f. (e) versus time $t$ is shown graphically by

Show answer and solution

Answer: (d)

Self-induced emf: $e = -L\frac{dI}{dt}$ .
$\frac{dI}{dt}$ is a positive constant, so $e$ is a constant negative value at all times.
The graph is a horizontal line below the time axis.
So the answer is (d).
