DT- electronics

Conductor

current flow, low resistance, free electrons

Battery

converts chemical energy into electrical energy

Photon

elementary particle responsible for electromagnetic phenomena; carries e.m. radiation -> LED's emit

Diode

allow current to flow in only one direction

Ionization

to gain or lose electrons

Load

motor, light -> uses electrical energy

Ohm's Law

V=IR -> used to make sure voltage/current levels are ok for a system

Generator

converts mechanical energy to electrical energy

Capacitor

store/release electrical charge

Resistance

limits current

Potentiometer

variable resistor

Electronics

study of the control of electron flow in a circuit

Current

flow of electrons in a wire or other conductor

Circuit

complete pathway for electrons

Insulator

material that blocks the flow of electrons

transistor

an electrical switch

valence electrons

electrons in the outermost shell of an atom

electromotive force

voltage, electrical pressure

potential difference

voltage, electrical pressure

Neg terminal to pos terminal

Electron Flow

pos terminal to neg terminal

Conventional (Hole) flow
