← ScienceWhich outcome accompanies a lossy dielectric between capacitor plates, energized by alternating voltage?
A)Increased equivalent series resistance✓
B)Higher resonant frequency oscillation
C)Reduced quadrature current component
D)Capacitance value remains unchanged
💡 Explanation
Increased series resistance appears because dielectric losses convert electrical energy into heat through dielectric relaxation, a frequency-dependent damping mechanism. Therefore equivalent series resistance increases, rather than the unchanged capacitive reactance or improved efficiency under resonance.
