← ScienceWhich risk increases when repeatedly switching a large inductive load?
A)Transient voltage exceeding component ratings✓
B)Ohmic heating increasing circuit resistance
C)Capacitive reactance limiting load current
D)Resonance creating harmonic distortion
💡 Explanation
Switching an inductive load causes large voltage spikes due to inductive flyback; the collapsing magnetic field induces a voltage according to Faraday's Law. High voltage destroys components, because energy dissipates as voltage spikes rather than driving the load efficiently.
