Term | Definition |
---|---|
electric force | The attraction or repulsion between electric charges. |
electric field | The region around a charged object where the object's electric force interacts with other charged objects. |
static electricity | A buildup of charges on an object. |
Conservation of Charge | The law that states that charges are neither created nor destroyed but only transferred from one material to another. |
electric current | The continuous flow of electric charges through a material. |
conductor | A material through which charges can easily flow, such as copper or silver. |
insulator | A material through which charges cannot easily flow, such as rubber or glass. |
voltage | The difference in electrical potential energy between two places in a circuit. |
resistance | The measurement of how difficult it is for charges to flow through a material. |
battery | A combination of two or more electrochemical cells in series. |
Ohm's law | The law that states that resistance is equal to voltage divided by current. |
series circuit | An electric circuit with a single path. |
ammeter | A device used to measure current in a circuit. |
parallel circuit | An electric circuit with multiple paths. Will allow lights to remain on if one bulb in circuit goes out. |
voltmeter | A device used to measure voltage, or electrical potential energy difference. |
power | The rate at which one form of energy is transformed into another; the unit of power is the watt. |
Watt | A measure of power equal to one joule of work per second. |
resistor | An electrical device that resists the flow of electrical current |
fuse | Electrical device that can interrupt the flow of electrical current when it is overloaded |
electrostatic charage | The study of electric charges that can be collected and held in one place. |
