an electrical property of matter that creates electric and magnetic forces and interactions | Electric charge |
a materialinwhich charges can move freely and that can carry an electic current | Electrical conductor |
a material that does not transdere current easily | Electric insulator |
the force of attraction or repulsion between objects due to charge | Electric force |
a region in space around a charge object that cause a stationary charge object to experence an electric force | electir field |
the ability to move an electric charge from one point to another | electrical potential energy |
between any two points the work that must be done against electric forces to move a unit charge fromone point to the other | potential differences |
a device that is a source of electric current because of a potential difference, or voltage, between the terminals | cell |
the rate that electric charge move through a conductor | current |
the opposition posed by amaterial or device to the flow of a current | resistance |
a set of electrical components connected such that they provide one or more complete paths for the movement of charges | electric circut |
a graphical representation of a circut that uses lines to represent wires and different symbols to represent components | schematic diagram |
the components of a circut that forms a single path forcurrent | series |
a circut in which all the components are connected to each other side by side | parallel |
the energy that is associated with chared particals because of their positions | electrical energy |
connected in series along the supply path | fuse |
a switch that opens a citcut automatically when the current exceeds a certain value | circut breakers |
