Self-Inductance & Energy

The current flowing through an inductor of selfinductance L is continuously increasing at constant rate. The variation of induced e.m.f. (e) verses $dI/dt$ is shown graphically by figure

Show answer and solution

Answer: (b)

$e = -L\frac{dI}{dt}$ : $e$ is directly proportional to $\frac{dI}{dt}$ with a negative constant $-L$ .
The graph must be a straight line through the origin going into negative $e$ .
That is graph (B), which is option (a).
