| Electricity flowing through metal with some difficulty | Heat |
| Measure of the rate of flow of electricity in a conductor | Amp |
| Used to measure a material's resistance to the flow of electrical current | Ohm's Law |
| Cuts off electricity if even tiny amounts of current leave the normal circuit | Ground Fault Interrupters |
| Electricity flows easily | Conductor |
| A source of electricity plus two or more wires connected to a load such as a light, heater, or motor: current cannot flow through it | Open Circuit |
| Measure of electrical pressure | Volt |
| Provides great resistance to the flow of electricity | Insulator |
| Electricity flowing through a conductor results in this | Magnetism |
| Measure of the amount of energy or work that can be done by amperes and volts | Watt |
| Making the additional connecton between a piece of equipment and the earth | Grounding |
