| Question | Answer |
|---|---|
| electric force | the attraction or repulsion between electric charges. |
| electric field | is a region around a charged object where the object's electric force is exerted on 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. |
| friction | The force that one surface exerts on another when two surfaces 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 means of the electric field of another object |
| static discharge | the loss of static electricity as electric charges transfer from one object to another |
| electric circuit | a complete, unbroken path through which electric charges can flow |
| conductor | a material through which charges can easily flow |
| insulator | a material through which charges cannot easily flow |
| voltage | the difference in electrical potential energy between two places in a circuit |
| voltage source | a device that creates an electrical potential energy difference in an electrical circuit |
| resistance | the measurement of how difficult it is for charges to flow through a material |
| chemical energy | a form of potential energy that is stored in chemical bonds between atoms |
| chemical reaction | the process in which substances undergo chemical changes that result in the formation of a new substance |
| electrochemical cell | a device that transforms chemical energy into electrical energy |
| electrode | a metal part of an electrochemical cell, which gains or loses electrons |
| electrolyte | a liquid or paste that conducts electric current |
| terminal | a convenient attachment point used to connect a cell or a battery to a circuit |
| battery | a combination of two or more electrochemical cells in a series |
| wet cell | an electrochemical cell in which the electrolyte is a liquid |
| dry cell | an electrochemical cell in which the electrolyte is a paste |
| Ohm's law | the law that states that resistance is equal to voltage divided by current |
| series circuit | an electrical circuit with a single path |
| ammeter | a device used to measure current in a circuit |
| parallel circuit | an electric circuit with multiple paths |
| 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 |
| short circuit | a connection that allows current to take an unintended path |
| grounded | allowing charges to flow directly from the circuit into Earth in event of a short circuit |
| third prong | the round prong of a plug that connects any metal pieces in an appliance to the safety grounding wire of a building |
| fuse | a safety device with a thin metal strip that will melt if too much current passe through a circuit |
| circuit breaker | a reusable safety switch that breaks the circuit when the current becomes too high |
