A conductor differs from an insulator in that a conductor
A) has faster moving molecules.
B) has more energy than an insulator.
C) has more protons than electrons.
D) has more electrons than protons.
E) none of these

Question

Quizplus · Accepted Answer

Conductors differ from insulators not because of the speed of their molecules, their energy content, or an imbalance in protons and electrons, but because of their ability to allow the flow of electric charge (usually due to the presence of free electrons or other charge carriers). None of the options A, B, C, or D accurately describe the fundamental difference between conductors and insulators.
