← ScienceWhich mechanism causes energy loss in dielectric material under alternating electric fields?
A)Frictional heating from dipole relaxation✓
B)Resistive losses from electron tunneling
C)Magnetic hysteresis within the material
D)Radiative losses due to field emission
💡 Explanation
When alternating electric fields are applied, dielectric polarization occurs as dipoles attempt to align with the changing field, but viscosity impedes their motion causing frictional heating. Therefore frictional heating is the result, rather than tunneling, hysteresis, or radiative losses, which depend on different material properties and conditions.
