| electric force | the attraction or repulsion beween electric charges. |
| electric field | The region around a charged object where the object's electric force interacts with other charge objects. |
| static electricity | A buildup of an object. |
| conservation of change | The law that states that charges are neither created nor destroyed but only transferred from one material to another. |
| friction | A method of charging an object by rubbing an object against another object; the force that one object exerts on another when the two rub against each other. |
| conduction | A method of charging an object by allowing electrons to flow by direct contact from one object to another object |
| induction | A method of charging an object by meansof the electric field of another object; the objects have no direct contact. |
| static discharge | The loss of static electricity as electric as charges transfer from one object to another. |
| electric current | The contuinuous flow of electric charges through a material. |
| electric circuit | A complete, unbroken path through which electric charges flow. |
| conductor | A meterial through which charges can flow easily. |
| insulator | A material through which charges cannot flow easily. |
| voltage | The difference in electrical potential energy between two places in a curicut |
| volatage source | A device that creates an electrical potential energy differences in an electric cuircut; batteries and generators are voltage sources. |
| resistance | The measurement of how difficuilt it is for charges to flow through a material. |
| chemical energy | The energy stored in chemical compounds. |
| chemical reaction | A process in which substances change into new sustances with different properties. |
| electrochemical cell | A device that transforms chemical energy into electrical energy. |
| electrode | A metal part of an electrochemicla cell, which gains or loses electrons. |
| electorlyte | A liquid or paste that conducts electric current. |
| terminal | A convenient attachment point used to connect a cell or battery. |
| battery | A combination of two or more electrochemical cells in series. |
| wet cell | An electrochemical cell in which the electrolyte is a liquid. |
| dry cell | An electronic cell in which the electrolyte is a paste. |
| Ohm's law | The law that states that resistance is equal to voltage 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. |
| voltmeter | The difference in electrical potential energy between two places in a ciruit. |
| power | The rate at which one form of energy is transformed into another; the unit of power is the watt. |
| short circuit | 27 |
| grounded | 28 |
| third prong | 29 |
| fuse | 30 |
| circuit breaker | 31 |
