Which failure results when capacitive reactance nears zero?

A)Reduced DC blocking effectiveness
B)Increased dielectric breakdown strength
C)Amplified transient voltage spikes
D)Oscillation frequency becomes uncontrolled

💡 Explanation

Reduced DC blocking occurs because decreased capacitive reactance at high frequencies allows DC current to pass; this bypasses the capacitor's intended function of blocking DC currents. Therefore, DC blocking fails, rather than voltage amplification or changing dielectric properties.
