← ScienceWhich outcome increases within a dielectric material used in a capacitor when subjected to a rapidly alternating electric field?
A)Dielectric heating✓
B)Charge carrier mobility
C)Capacitance stability
D)Electrostatic shielding
💡 Explanation
Dielectric heating increases because polarization switching at the molecular level generates friction and heat via dielectric losses. Therefore, dielectric heating rises with AC fields, rather than increased shielding or direct effects on charge mobility, because AC fields cause constant polarization reversals.
