circuit | closed conducting loop in witch electric current can flow continually. |
conductor | material in witch electrons can move easily |
electric current | the flow of electric charge,measured in amperes. |
electric discharge | rapid movement of excess charge from one place to another |
electric field | surrounds every electric charge and exerts forces on other electric charge |
electric force | attractive or repulsive force exerted by all charged objects on each other |
electric power | rate at which electrical energy is converted in to others forms or energy, measured in watts or kilowatts . |
insulator | material in which electrons cannot move easily |
ohm's law | states that the current in a circuit equals the voltage divided by the resistance in the circuit. |
parallel circuit | circuit that has more than one path for electric current to follow |
resistance | a measure of how difficult it is for electrons to flow it is for electrons to flow in a material ;unit is this ohm |
series circuit | circuit that has only one path for electric current flow to follow |
static charge | imbalance of electric change on an object |
voltage | measure of the difference in electric potential between two points in space, a material, or an electronic circuit, expressed in volts |
ion | positively or negatively charged atoms |
