← ScienceWhich effect occurs when an AC signal's frequency nears a ceramic capacitor's self-resonant frequency?
A)Capacitive reactance decreases dramatically✓
B)Oscillations transition into critical damping
C)Effective series resistance plateaus
D)Dielectric breakdown risk diminishes
💡 Explanation
Capacitive reactance decreases sharply due to series resonance; the inductance from the capacitor leads and plates cancels the capacitance. This causes a significant reduction, because the impedance approaches zero therefore increasing current, rather than leading to plateauing resistance changes or damping.
