Science

Which effect arises inside a cable incorporating an insufficiently thick dielectric material when subjected to high-frequency alternating current?

A)Increased dielectric absorption occurs
B)Skin effect reduces conductivity
C)Cable inductance sharply decreases
D)Ferrite core saturation becomes maximal

💡 Explanation

Increased dielectric absorption occurs because at high frequencies polarization cannot keep pace with the changing electric field, therefore energy is dissipated as heat rather than stored in the capacitance of the cable, rather than lossless propagation.
