Consider two inductor circuits. Assume that the current is increasing with time equally in both the circuits. The correct graph for energy stored in inductor with current is

$ \frac{di}{dt} = k$ $ I = kt$ We know, Energy stored in an Inductor U = \(\frac{1}{2}\)Ll2 Thus U ∝ I2 → quadratic function and U ∝ L Hence, upward parabolic curve and
