Assertion If current shown in the figure is increasing, then Reason IF current passing through an inductor is constant, then both ends of the inductor are at same potential.

Two different coils have self inductances L_1=9mH and L_2=2mH . The current in one coil is increased at a constant rate. The current in the second coil is also increased at the same constant rate. At a certain instant of time, the power given to the two coils is the same. At that time, the current the induced voltage and the energy stored in the first coil are i_1,V_1 and W_1 respectively. Corresponding values for the second coil at the same instant are i_2,V-2 and W_2 respectively. Then,

Two different coils have self-inductances L_(1) = 8 mH and L_(2) = 2 mH . The current in one coil is increased at a constant rate. The current in the second coil is also increased at the same constant rate. At a certain instant of time, the power given to the two coil is the same. At that time, the current, the induced voltage and the energy stored in the first coil are i_(1), V_(1) and W_(1) respectively. Corresponding values for the second coil at the same instant are i_(2), V_(2) and W_(2) respectively. Then:
