| Term | Definition |
|---|---|
| electromagnetism | interaction of energy and magnetism |
| charge | inbalance of electrons and protons; something is electrically charged if it has a build up of electrons (and is negatively charged) |
| conduction | transfer of electrical charge through direct conduct or touching; between an uncharged and charged object |
| induction | transfer of electrical charge through INDIRECT conduct No touching- rearranging of electrons but no contact; between charged and uncharged objects |
| friction | transfer of electrical charge through rubbing or wiping electrons from one object to another; both uncharged objects |
| current | movement of electrons |
| alternating current | movement of electrons are moving in changing directions; can move long distances |
| direct current | movement of electrons in one direction; short distances- batteries |
| voltage | measurement of stored up electricity; potential strength of electricity available |
| amperage | the measurement of current- how fast the electrical current is moving |
| ohm | SI Unit that measures resistance |
| resistance | something that opposes current or slows it down (anything in the circuit that is using electricity is resistance) |
