← TechnologyWhich outcome occurs when an inductive load switches off in a power distribution system without surge protection?
A)Voltage spikes damaging circuit insulation✓
B)Current harmonics distorting power waveform
C)Resonance causing sustained oscillations
D)Overheating neutrals inducing eddy currents
💡 Explanation
When an inductive load is switched off, the collapsing magnetic field induces a large voltage spike due to Lenz's Law, potentially exceeding the insulation's dielectric strength. Therefore, voltage spikes result that damage circuit insulation rather than distortion, oscillation, or overheating, requiring corresponding mechanisms and conditions.
