← ScienceWhat outcome occurs when an EMP passes a charged capacitor?
A)Induced voltage causes dielectric breakdown.✓
B)Increased capacitance lowers resonant frequency.
C)Charge accumulates due to ohmic resistances.
D)Reduced impedance avoids surface accumulation.
💡 Explanation
The EMP's electromagnetic pulse induces a voltage (Faraday's law) exceeding the capacitor's dielectric strength; this results in dielectric Breakdown, because electron avalanching overwhelms the insulator. This breakdown happens due to overvoltage rather than changes in capacitance or impedance.
