  1. Question 1

    Q1. A choke coil is used to control current in an AC circuit. It is preferred over a resistor because it

    • A) Increases the current
    • B) Decreases the current without power loss
    • C) Increases the power factor
    • D) Decreases the impedance

    Answer: Decreases the current without power loss

    Explanation: A choke coil (inductor) controls current without significant power loss; 'Increases the current' is the opposite effect.
