The correct statement regarding electric insulators is:
a. Charges within electric insulators do not readily move.
Electric insulators are materials that do not allow electric charges to flow freely, making it difficult for electrical current to pass through them. This means that the charges within these materials are largely static and do not move readily.
The other statements are incorrect:
- b. Electric insulators are generally poor heat conductors, not good ones.
- c. Electric charges do not move freely in electric insulators.
- d. While some insulators may have high tensile strength, this is not a defining characteristic of electric insulators in general.
