Which statement about electric insulators is true?
A Electric insulators have a high flow of heat and electricity.
B Electric charges move freely in electric insulators.
C Charges within electric insulators do not readily move.
D Electric insulators are the best heat conductors.
C Charges within electric insulators do not readily move.
The correct statement about electric insulators is:
C Charges within electric insulators do not readily move.
The correct statement about electric insulators is C) Charges within electric insulators do not readily move.
To understand why this statement is true, we need to know what electric insulators are and how they work. Electric insulators are materials that do not allow the easy flow of electric charges. Unlike conductors, which allow electric charges to move freely, insulators restrict the movement of charges. This is due to the atomic or molecular structure of insulating materials, which does not have loosely bound electrons that can easily move around.
To arrive at this conclusion, you could eliminate the other options:
A) Electric insulators have a high flow of heat and electricity.
This is incorrect because electric insulators are known for their low conductivity of heat and electricity. They resist the flow of both.
B) Electric charges move freely in electric insulators.
This is also incorrect. As mentioned earlier, insulators restrict the movement of electric charges rather than allowing them to move freely.
D) Electric insulators are the best heat conductors.
This is incorrect because insulators actually have poor heat conductivity. They are used to avoid heat transfer and protect against the flow of electricity.
By eliminating the incorrect statements, we can conclude that the true statement is C) Charges within electric insulators do not readily move.
