an electrical property of matter that creates electric and magnetic forces and interactions | electric charge |
a material in which charges can move freely | electrical conductor |
a material in which charges cannot move freely | electrical insulator |
the force of attraction or repulsion on a charged particle that is due to an electric field | electric force |
the ability to move an electric charge from one point to another | electrical potential energy |
the voltage difference in potential between two points in a circuit | potential difference |
a device that produces an electric current by converting chemical or radiant energy into electrical energy | cell |
