Q: What is the primary function of an inductor in an electrical circuit?

To store energy in a magnetic field. — Inductors store energy in the magnetic field created around their windings when current flows.

Q: The unit of inductance is the:

Henry (H) — Inductance, represented by the symbol L, is measured in Henrys.

Q: What happens to the current through an inductor when the voltage across it is constant?

The current increases linearly. — With constant voltage, the current through an inductor increases linearly, because the voltage is proportional to the rate of change of current (di/dt).

Q: How is the inductance of an inductor affected by the number of turns of wire in its coil?

It is directly proportional to the square of the number of turns. — Inductance increases significantly with more turns; it's proportional to the square of the turns.

Q: What is the equivalent inductance of two inductors connected in series?

The sum of their individual inductances. — Inductors in series behave much like resistors in series; their total inductance is the sum of their individual inductances.
