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

# data[].attributes.body
The closer the positive charge, the stronger the voltage.

# data[].attributes.body
The further the negative charge, the stronger the voltage.

# data[].attributes.body
The further from the positive charge and closer to the negative charge, the weaker the voltage. The closer to the positive charge and further from the negative charge, the stronger the voltage.
