Respuesta :
An insulator does not have electrons that are free to move, and a conductor does.
The difference between an insulator and a conductor is defined by the statement D.
A conductor has electrons to transmit the energy while an insulator does not.
Difference between Insulator and Conductor
The conductors contain electrons to transfer energy. These electrons move freely in a conductor. When the charge is transferred to a conductor, it allows electrons to carry that charge and distribute across the entire surface of the conductor. This is known as electron movement.
Insulators contain atoms that are highly bonded and not ready to move easily. When the charge is transferred to an insulator, it does not allow electrons to carry that charge and the charge will remain at its initial location. The electrons are highly bonded with each other that they are not ready to move.
Hence we can conclude that an insulator does not permit its electron to transmit the charge.
