← ScienceWhich outcome occurs when a high-frequency signal stresses an imperfect capacitor?
A)Dielectric heating elevates internal temperature✓
B)Electrostatic discharge erodes electrode surfaces
C)Capacitance increases due to dielectric saturation
D)Impedance decreases, approaching short circuit
💡 Explanation
Dielectric losses convert AC energy to heat via dielectric relaxation. This leads to internal heating because the electric field causes polarization changes, therefore, internal heating happens rather than arcing. Saturation and low impedance relate less strongly to imperfections.
