Which effect occurs when a capacitor is used at frequencies approaching its series resonant frequency?

A)Capacitive reactance becomes inductively dominant
B)Dielectric breakdown risk is minimized
C)Equivalent series resistance drops sharply
D)Self-resonant frequency shifts downwards

💡 Explanation

Inductive reactance leads when a capacitor is near its series resonant frequency, because impedance transitions from capacitive to inductive due to series resonance, therefore the reactance becomes inductively dominant, rather than remaining capacitive under usual load.
