← ScienceWhich consequence results when parasitic inductance dominates capacitively ballasted LEDs?
A)Resonance causes overvoltage spikes✓
B)Thermal runaway leads to failure
C)Lower luminous efficacy occurs gradually
D)Electromagnetic interference reduces reliably
💡 Explanation
Resonance creates excessive voltage spikes if parasitic inductance overwhelms suppression from capacitance; this is because the impedance minimizes at a specific frequency. Therefore overvoltage occurs, spiking the components and leading to premature failure, rather than gradual failure or reduced radio emissions.
