Electricity

Think:Can you think of anything that

uses electricity?

Electricity is Everywhere

• In your home, electricity runs the lights, television, toaster, machines, heats, and does much more. It’s hard to even imagine what your life would be like without it.

• What is electricity?

Energy

• Electricity is another kind of energy.• It travels through wires to your home.• We will learn about two types of

electricity: current electricity and static electricity.

• Current electricity goes from one place to another.

• Static electricity stays in one place.

This is Current Electricity

2. The power plant sends electricity through power lines. Overhead power lines carry electricity to  transformers  on poles.

3. From transformers, electricity travels into houses and buildings through wires.

1. Electricity travels in a circuit that begins at a power plant.

4. Electricity flows from the wires in the wall to the outlet, then to the appliance cord.

5. When you plug something in and turn it on you complete electricity’s circuit.

Current electricity goes from one place to another.

Batteries

• People also get electric energy from batteries.• We use batteries to get electricity into objects

that are not connected to a wall plug.• This electric energy is used for many things.

– toys– radios– cameras– flashlights– watches– cars

Complete Circuit

• In order for electricity to travel to where we need it, there must be a complete circuit of electricity. A complete circuit is like a circle.

• A circuit is a closed path so electricity can follow.

• Electricity starts at a particular place, travels around the circuit, and returns to the same place.

• No circuit will work if it has a break in it.
