Term | Definition |
---|---|
electrical potential energy | potential energy associated with a charge due to its position in an electric field |
electric potential | the work that must be performed against electric forces to move a charge from a reference point to the point in question divided by the charge |
potential difference | the work that must be performed against electric forces to move a charge between the two points in question, divided by the charge |
capacitance | the ability of a conductor to store energy in the form of electrically separated charges |
electric current | the rate at which electric charges pass through a given area |
drift velocity | the net velocity of a charge carrier moving in an electric force |
resistance | the opposition presented to electric current by a material or device |
schematic diagram | a representation of a circuit that uses lines to represent wires and different symbols to represent components |
electric circuit | a set of electrical components connected such that they provide one or more complete paths for the movement of charges |
series | describes two or more components of a circuit that provide a single path for current |
parallel | describes two or more components of a circuit that provide separate conducting paths for current because the components across common points or junctions |
