B)square of the root-mean-square (RMS)current
C)root-mean-square (RMS)voltage
D)square of the root-mean-square (RMS)voltage

Question

Quizplus · Accepted Answer

The value of energy (heat) generated during a fault varies as the square of the root-mean-square (RMS) current multiplied by the time (duration of fault) in seconds. This is because the energy dissipated in an electrical circuit due to a fault is proportional to I^2R (where I is the RMS current and R is the resistance), and since energy is power (P = I^2R) times time, the relevant factor is the square of the RMS current.
