The voltage rating of wire is determined by ____.
A) the type of material of which the wire is made
B) the type of insulation
C) its diameter
D) its weight

Question

Quizplus · Accepted Answer

The voltage rating of wire is determined by the type of insulation. Different types of insulation have different maximum voltage ratings based on their dielectric strength. The diameter and weight of the wire may affect its current-carrying capacity, but not its voltage rating. The type of material used to make the wire may affect its overall conductivity but not necessarily its voltage rating.
