  1. Question 1

    Q1. A transformer has a low resistance coil. What is the effect of the low resistance coil on the magnetic field?

    • A) The magnetic field increases with the low resistance coil.
    • B) The magnetic field remains constant with the low resistance coil.
    • C) The magnetic field decreases with the low resistance coil.
    • D) The magnetic field is independent of the low resistance coil.

    Answer: The magnetic field increases with the low resistance coil.

    Explanation: The magnetic field increases with the low resistance coil, as the current in the coil increases due to the low resistance, and the magnetic field is proportional to the current.
