  1. Question 1

    Q1. A choke coil (inductor) in a fluorescent light circuit drops voltage without power loss. Why is this possible?

    • A) Inductive reactance opposes current without dissipating energy.
    • B) The circuit’s resistance is bypassed by the choke.
    • C) Voltage across the inductor is always zero.
    • D) Inductors convert electrical energy to magnetic fields permanently.

    Answer: Inductive reactance opposes current without dissipating energy.

    Explanation: Inductive reactance stores energy in a magnetic field. D is incorrect because energy is returned to the circuit.
