The frame of an electric motor is earthed through three earthing plates resistances 30 Ω, 20 Ω and 10 Ω respectively. During fault the energy dissipated by three plates are W1, W2 and W3. Then
W1 > W2 > W3
W1 < W2 < W3
W1 = W2 = W3
W1 + W3 < W2
Answer: Option
Explanation:

Energy dissipated by the plate with lowest resistance is maximum.
