Can we get those electrons moving? Chapter 17 Can we get those electrons moving?

Induction The transfer of electron or electricity without touching

A group of cells put together BATTERy A group of cells put together

Electric Discharge The release of electricity from a source – like a cumulonimbus cloud

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.

Law of electric charges Likes repel and opposites attract.

Insulator Materials that don’t let heat move freely

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 Energy difference between per unit of Charge is known as potential difference

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. LOAD – any device that uses Electricity to work Switch – a device that opens and Closes a circuit

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