Which statement about electric insulators is true?

Question

charges within electric insulators do not readily move
electric charges move freely in electric insulators
electric insulators are the best heat conductors
electric insulators have a high flow of heat and electricity

Answer 1

The true statement about electric insulators is:

Charges within electric insulators do not readily move.

Electric insulators do not allow electric charges to flow freely, which means that charges are generally fixed in place and do not move easily within the material.
