← ScienceWhich outcome occurs when a high-frequency electromagnetic field induces resonant oscillations within a dielectric?
A)Increased dielectric heating occurs quickly✓
B)Dielectric strength greatly rises instead
C)Charge carrier mobility stays constant
D)Capacitance sees negligible change
💡 Explanation
Increased dielectric heating results from the dielectric loss mechanism when the material polarization lags the oscillating field, because more electrical energy is transformed into kinetic energy; therefore internal temperature climbs rather than strengthening the substance.
