The incorrect statements is/are

A) The resistance offered by an inductor in a d. c circuit is always constant.

B) The resistance of inductor in steady state is zero.

C) An inductor is connected to a battery through a switch. The emf induced in the inductor is much larger when the switch is opened as compared to the emf induced when the switch is closed.

D) To reduce the rate of increases of current through a solenoid should increase the time constant\[\left( \frac{L}{R} \right)\].
