How does an insulator stop the flow of an electric current?

a. insulators have too many electrons.

b. insulators have a positive charge so they absorb electrons.

c. electrons in an insulator do not move readily.

d. insulators convert electric energy to other forms of energy.

I believe the correct response would be C. Electrons in an insulator do not move readily thus affecting the flow of electric current.

The correct answer is C. Insulators stop the flow of an electric current because its electrons do not move readily. The electrons are strongly attracted to bonds thus there are no easily movble electrons, hence no electric current.

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
