Electricity

1. the process of making an electrical connection between a circuit,electricity-using device, or other electricity source to the earth to reduce the chance of shock and damage.
3. a measure of energy available or work that can be done using one ampere at one volt.
4. a measure of the resistance of a material to the flow of an electrical current.
7. form of energy that can produce light,heat,magnetism, and chemical changes.
8. loss of voltage as electricity travels through a wire.
9. any material that will permit an electron to move through it.
10. a switch that trips and breaks the circuit when more than a specified amount of current passes through it.
13. protective tube with individual insulated wires running through it.
14. a measure of electrical pressure.
15. a measure of the rate of flow of a current in a conductor.
16. electrical source and wires connected to an electrical device.

2. a standard for the safe installation of electrical wiring and equipment.
5. a condition that occurs when electricity flows back to its source to rapidly and trips,fuses,burn wires, and drains batteries.
6. the use off watts per hour.
11. material that provides great resistance to the flow of electricity.
12. any tendency of a material to prevent electrical flow.
