| electric charge | property that causes particles such as protons and electrons to attract or repel each other |
| net electric charge | produced by a excess or shortage of electrons |
| electricity | form of energy; flow of electrons |
| electric force | the force of attraction or repulsion between electrically charged objects |
| electric field | the effect an electric charge has on other charges in the space around it; it's strength depends on the amount of charge that produces the field and on the distance from the charge |
| static | stationary electrical charges |
| static discharge | occurs when a pathway through which charges can move forms suddenly |
| law of conservation of charge | the total charge is the same before and after the transfer of charge occurs |
| electric current | continuous flow of electric charge; measured in amperes or amps |
| conductor | a material through which charge can flow easily |
| insulator | a material through which charge cannot flow easily |
| resistance | opposition to the flow of charges ina material; measured in ohms |
| superconductor | a material that has almost zero resistance when it is cooled to low temperatures |
| voltage | potential difference or the difference in electrical potential energy between 2 places in an electric field; unit of measure is called volts |
| ohm's law | V(volts) = I(amps) x R(ohms) or (voltage = current x resistance) |
| electrical circuit | a complete path through which charge can flow |
| electric power | P(watts) = I (amps) x V (volts). Power is the rate of doing work. Electric power is the rate at which electrical energy is converted to another form of energy |
| magnetic force | the force a magnet exerts on another magnet |
| magnetic pole | regions where the magnet's force is strongest |
| magnetic field | surrounds a magnet and can exert magnetic forces |
| electromagnetic force | a single force of which electricity and magnetism are different aspects/phases of |
| AC or alternating current | the flow of electric charge that regularly reverses it's direction |
| DC or direct current | charge that flows in only one direction |
| series circuit | a circuit that has only one path through which charges can |
| parallel circuit | circuit with 2 or more paths through which charges can flow |
