| A | B |
| Circuit | Closed, unbroken path through which and electric current can flow |
| Conductor | Material, such as copper, silver, and iron, through which electrons can move easily |
| Electric current | Contiunous flow of electrons through a conductor; measured in units amperes (A) |
| Electric Discharge | Rapid movement of excess electrons from one place to another |
| Electric power | Rate at which an appliance converts electrical energy |
| Insulator | Material, such as rubber or glass, through which electrons cannot move easily |
| Ohm's law | Relationship between voltage, current, and resistance in an electric circuit; V=IR, where V represents the voltage, I represents the electrical current, and R represents the resistance |
| Parallel circuit | Circuit that has more than one path for the electric current to follow |
| Resistance | Measure of how difficult it is for electrons to flow through a material; unit is the ohm |
| Series circuit | Circuit that has only one path for the electric current to follow |
| Static charge | Buildup of electric charges in one place |
| Voltage | Measure of electric potential energy; measured in units of volts (V) |
