Vocabulary

Electricity - movement of charged particles in a conductor

Electron – negatively charged particle

Battery - chemically creates electricity

Battery cell - a single unit of electrodes and electrolyte – NOT hooked together

Electrode - material that can create a voltage potential in a battery

Electrolyte - material that allows for the passage of charged particles in a battery

Positive - attracts electrons; also marked by RED

Watts - measurement of power; in electricity it is Watts = Amps x Volts

Parallel - multiple paths for the electricity to flow in a circuit
Negative - gives up electrons; also the color BLACK and called ‘ground’ or GND

Circuit – connecting a load (lights, motors, heaters) to the positive and negative of a power source

Short circuit - directly connecting the positive and negative of an electricity source

Voltage - the pressure that makes electrons move. Measured in Volts (V)

Resistance - resistance to current flow: Measured in Ohms (Ω)

Current - movement of electrons: Measured in amperes (I)

Ohms Law - the relationship between Volts, Amps and Ohms: Volts = Amps x Ohms

Series - single path for the electricity to flow in a circuit
