Which mechanism causes increased heat generation within oscillating inductive heater circuits during capacitor aging?

A)Increased equivalent series resistance
B)Decreased dielectric breakdown voltage
C)Elevated resonant frequency drift
D)Enhanced skin effect penetration

💡 Explanation

Capacitor aging increases the equivalent series resistance (ESR), leading to more heat generation because a larger ESR causes increased Ohmic losses during each voltage swing during the capacitor's charge/discharge cycle; therefore, option A is correct, rather than breakdown voltage or frequency shifts on skin effect changes.
