Physical Sciences & Mathematics

A transformer's primary coil suddenly shorts to the secondary coil. Which consequence follows regarding energy transfer?

A)Increased reactive power demand occurs
B)Voltage regulation improves significantly
C)Eddy current losses are minimized quickly
D)Energy transfer becomes uncontrolled, destructive

💡 Explanation

Uncontrolled energy transfer and potential destruction occur because the short circuit bypasses the inductive impedance, resulting in a surge of current due to minimal impedance; therefore, energy is dumped rapidly rather than controlled by inductive reactance.
