| The potential energy associated with a charge due to its position in an electric field. | Electric Potential Energy |
| The work that must be performed against electric forces to move a charge between the two points in question, divided by the charge. | Potential difference |
| A device that is used to store electrical potential energy. | Capacitor |
| The ability of a conductor to store energy in the form of electrically separated charges. | Capacitance |
| The SI unit for capacitance; equals a coulomb perr volt. | Farad |
| The rate at which electric charges pass through a given area. | Current |
| The opposition presented to electric current by a material or device. | Resistance |
| The SI unit for resistance; equal to one volt per ampere. | Ohm |
| Material whose resistance is constant over a range of potential differences. | Ohmic material |
| Material whose resistance is not constant over a range of potential differences. | Non-ohmic material |
| A device that can be used to control the amount of current in a conductor. | Resistor |
| A special type of resistor that can be used to vary the resistance. | Potentiometer |
| A current in wich charges move in a single direction. | Direct current |
| A current in which the direction of charge movement continually alternates. | Alternating current |
| The rate of conversion of electrical energy. | Electric power |
| Used by electric companies to measure energy consumption. | Kilowatt-hours |
