Static electricity Electric charges that are at rest

Electric field The space around a charged object

Electric force How much a attraction or repulsion an object has.

conductor A materials that lets charges flow freely.

Electric current How fast does a charge move past a given point Measured in amps

voltage how much difference could be between two points

Resistance Anything that slows down the movement of current

cell A device that produces a current by converting chemical or radiant energy into electricity

photocell Device that converts light into electrical energy

thermocouple Changes heat into electrical energy

Electric power The rate at which Electricity is changed Into other forms

Series Circuit A circuit where parts are joined one after another.

Parallel Circuits A circuit where the parts are joined in branches.
