  1. Question 1

    Q1. The magnetic flux through a coil changes from 0.02 Wb to 0.08 Wb in 0.1 s. If the coil has 200 turns, what is the average induced EMF?

    • A) 12 V
    • B) 16 V
    • C) 20 V
    • D) 24 V

    Answer: 12 V

    Explanation: Average induced EMF = N*dΦ/dt = 200*(0.08-0.02)/0.1 = 12 V. Option B fails due to miscalculation.
