  1. Question 1

    Q1. A transformer is used to increase the voltage of an alternating current. What is the primary mechanism responsible for this increase in voltage?

    • A) The transformer uses a magnetic core with a high magnetic permeability to concentrate the magnetic field.
    • B) The transformer relies on electromagnetic induction to transfer energy between coils.
    • C) The transformer employs a high number of turns in the secondary coil to step up the voltage.
    • D) The transformer uses a capacitor to store electrical energy and release it at a higher voltage.

    Answer: The transformer employs a high number of turns in the secondary coil to step up the voltage.

    Explanation: The transformer increases voltage by using a high number of turns in the secondary coil, leveraging electromagnetic induction to concentrate the magnetic field.
