1. 4. OK, but if I had the choice I would say "mechanical" energy

5. I do not think so. You want a poor conductor for an "insulator".

For a resistance you usually use a reasonable conductor but make it thin.

4. 4.mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.charge. so number 4 is wrong.

5. Guys let's take a close look at this ok so basically it's saying what uses a short amount of electricity a ressitor is the resistance to the passage of a electrical current so i would say C . Switch because a switch cuts off electrical currents
