Which of the following statements regarding electric insulators is correct?
a
Electric insulators have high tensile strength.
b
Electric charges move freely in electric insulators..
c
Charges within electric insulators do not readily move.
d
Electric insulators are good heat conductors.
The correct statement regarding electric insulators is:
c. Charges within electric insulators do not readily move.
Electric insulators have high resistivity, which means they resist the flow of electric charges. This is what makes them effective in insulating against currents.
