Lesson 01 – Using Electricity

Read About Using Electricity


Read the vocabulary terms to understand the reading better.


Batteries are devices that contain one or more electric cells that store chemical energy that can be used to produce electricity.


Coal is a black or dark brown substance produced underground from long dead plants; coal can be burned as fuel or burned to produce electricity.


Electricity is a form of energy that has positive and negative forms that occur naturally (such as in lightning) or can be produced (such as in a generator) and is the result of electrons moving and interacting together.


Energy is the ability or power to do work.


Generators are machines that transform one form of energy into another; for example, changing mechanical energy such as wind or steam into electrical energy.

Natural Gas

Natural gas is a form of liquid fuel that is found underground in petroleum deposits and is burned as fuel or burned to produce electricity.

Power Plant

A power plant is a group of buildings, equipment, and machinery that are used to generate electricity from another source of energy such as a hydroelectric dam.

Transmission Lines

Transmission lines are power lines or cables that transmit electricity from a generating station to electrical towers and poles, that then transmit the electricity through electrical wires to houses and other buildings.

Using Electricity

Electricity is a form of energy that we use in many ways every day. You probably use electricity much more than you realize. Look at the pictures. Think about which things use electricity.

Electricity provides the energy that makes devices work. Some devices get electricity from batteries. Other devices get electricity from a wall outlet. You plug the device into the outlet and electricity travels into the device through the wire.

Where Does Electricity Come From?

Electricity is produced in a power plant by machines called generators. The generators are powered by a fuel such as coal or natural gas. Generators can also be powered by wind or water.

The electricity produced by the power plant travels over wires called transmission lines. Some of these transmission lines are attached to tall metal towers, and others are attached to poles along streets. In many places, electrical wires are buried underground. The wires provide electricity to homes, schools, factories, and other buildings.
