Question | Answer |
the accumulation of excess electric charge on an object | static electricity |
states that charge cannot be created or destroyed and charge can be transferred from one object to another | Law of Conservation of Charge |
material where electrons can move freely | conductor |
material in which electrons aren't able to move easily | insulator |
the net movement of electric charges in a single direction, measured in amperes | electric current |
related to the force that causes electric charges to flow; measured in volts | voltage difference |
closed conducting loop through which an electric current can flow | circuit |
tendency for a material to oppose electron flow and change electrical energy into thermal energy and lights; measured in ohms | resistance |
states that the current in a circuit equals the voltage difference divided by the resistance | ohm's law |
circuit in which electric current has only one path to follow | series circuit |
circuit in which electric current has more than one path to follow | parallel circuit |
rate at which electrical energy is converted to another form of energy; expressed in watts | electrical power |
