Faraday's Law CalculationMediumQuestion 20211

Question

Flux through a 100-turn coil changes from 0.05 Wb to 0.01 Wb in 0.02 s. Induced EMF is:
  1. A
    2 V
  2. B
    200 V
    Correct
  3. C
    0.02 V
  4. D
    20 V

Correct answer

200 V

Explanation

EMF = −N(ΔΦ/Δt) = −100 × (0.01−0.05)/0.02 = −100 × (−2) = 200 V.
