| 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 seperate conducting paths for current because the components are connected across common points or junctions |
