Which of the following statements about inductors are correct?
A) When an inductor and a resistor are connected in series with a DC battery, the current in the circuit is reduced to zero in one time constant.
B) When it is connected in a circuit, an inductor always resists having current flow through it.
C) An inductor always resists any change in the current through it.
D) When an inductor and a resistor are connected in series with a DC battery, the current in the circuit is zero after a very long time.
E) Inductors store energy by building up charge.
