Please show all work and specify the correct answer at the bottom. Do not put down an answer that is not one of the choices.

Which of the following statements about inductors are correct?

An inductor always resists any change in the current through it. When it is connected in a circuit, an inductor always resists having current flow through it. 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. 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. Inductors store energy by building up charge.

Explanation / Answer

An inductor, also called a coil or reactor, is a passive two-terminal electrical component which resists changes in electric current passing through it. It consists of a conductor such as a wire, usually wound into a coil. Energy is stored in a magnetic field in the coil as long as current flows.

Therefore,

Option A
