appliance - a machine or piece of equipment that performs a task

battery - a device that contains one or more cells -- stores and converts chemical energy into electrical energy -- has positive and negative terminal

bulb - a glass container that converts electricity into light -- has piece of metal inside that lights up when an electrical current passes through it

buzzer - a device that makes a low, continuous humming sounds when an electrical current passes through it

cell - a single unit that produces chemical energy which converts into electrical power -- has a positive and negative terminal -- a battery is made up of one or more of these cells

circuit - a closed loop or path around which an electrical current can flow

component - the parts of an electrical circuit -- components must be connected properly to allow electrical current to flow through them -- examples would be cell, motor, resistor, and switch

conductivity - the degree to which something allows an electrical current to flow through it

conductor - something that allows an electrical current to pass through it -- examples include items made from metal

connection - occurs when electrical components are linked to each other, therefore allowing an electrical current to flow

current - a flow of electricity

device - something that has been made or modified for a particular purpose

electron - a tiny particle that has a negative electrical charge

fuse - a device that breaks an electric circuit if the current exceeds a safe level

insulator - something that does not allow an electrical current to pass through it - examples include wood or plastic

motor - a machine that is powered by electricity and supplies power to a device with moving parts

power - the rate of electrical energy that is passed through a circuit

resistance - the degree to which the flow of electrical current through a circuit is slowed or stopped

resistor - an electrical component that limits the amount of electrical current that can flow through a circuit

short circuit - occurs when the electrical current flows doesn't a wrong or unintended part of the circuit and causes damage to the circuit

switch - an electrical component that can be open or closed to interrupt or allow the flow of electricity through a circuit

terminal - a terminal is the part of the cell that makes the electrical connection with the rest of the circuit -- a cell has a positive and a negative terminal

voltage - the force of an electrical current -- measured in volts

wire - a thin, flexible, string-like thread -- wire is made from metal as it is a good conductor of electricity
