| electric charge | is a property that causes subatomic particles such as protons and elctrons to attract or repel each other |
| electric force | the force of attraction or repulsion between electricallyh charged objects |
| electric field | the effect an electric charge has on other charges in the space around it is the charges |
| static electricity | is the study of the behavior of elctric charges, including how chare is transferred between objects |
| law of conservation of charge | the total charge in an isolated system is constant |
| induction | transfer of charge without contact between materials |
| electri current | continuous flow of electric charge |
| direct current | charge flows only in one direction |
| alternating current | is a flow of electric charge that regularly reverses its direction |
| electrical conductor | is a material through which charge can flow easily |
| electrical insulator | a material through which charge cannot flow easily is |
| resistance | is opposiont to the flow of charges in a material |
| superconductor | is a material that has almost zero resistance when it is cooled to low temperatures |
| potential difference | is the differce in electrical potential energy between two places in an electric field |
| voltage | another name for potential difference |
| battery | is a device that converts chemical energy to electrial energy |
| Ohm's law | the voltage in a circuit equals the product of the current and the resistance |
| electric circuit | is a complete path through which charge can flow |
| series circuit | charge has only one path through which it can flow |
| parallel circuit | is an elctric circuit with two more paths through which charges can flow |
| electric power | the rate at which electrical energy is converted to another form of energy |
| fuse | prevents current overload in a circuit |
| circuit breaker | is a switch that opens when current in a circuit breaker is too high |
| grounding | transfer of excess charge through a conductor to Earth |
| electronics | science of using electric current to process or transmit information |
| electronic signal | is information sent as patterns in the controlled flow of electrons through a circuit |
| analog signal | is a smoothly varying signal produced by continuously changing the voltage or current in a circuit |
| digital signal | encodes information as a string of 1's and 0's |
| semiconductor | is a crystalline solid that conducts current only under certain conditions |
| diode | is a solid state component that combines an n-type and a p-type semiconductor |
| transistor | a solid-state component with three layers of semiconductors |
| integrated circuit | is a thin slice of silicon that contains many soli-state components |
| computer | is a programmable device that can store and process information |
