  1. Question 1

    Q1. The magnetic flux through a 50-turn coil changes from 0.05 Wb to 0.15 Wb in 0.2 s. What is the average induced EMF?

    • A) 12.5 V
    • B) 25 V
    • C) 37.5 V
    • D) 50 V

    Answer: 25 V

    Explanation: Average induced EMF = N*dΦ/dt = 50*(0.15-0.05)/0.2 = 25 V. Option A fails due to miscalculation.
