When you take off your wool hat, it rubs against your hair.
Electrons move from your hair to the hat.
A static charge builds up and now each of the hairs has the same positive charge.
Remember, things with the same charge repel each other. So the hairs try to get as far from each other as possible. The farthest they can get is by standing up and away from the others. And that is how static electricity causes a bad hair day!
What is a conductor?
Conductors Allows electric energy/current to flow through it Best conductors are Silver Gold Copper Is Water a Conductor?
What is an insulator?
Insulators Restrict (stop or limit) the flow of electricity through it Some insulators are: Paper Plastic Glass Ceramic
How a Wire Works…
A Battery is… A container full of chemicals that produce electrons. These electrons produce energy. Where do you use batteries?
Light Bulb Turns electricity into light through the filament inside the glass bulb. What is the insulator? What is the conductor?
Types of Circuits Open Circuits Closed Circuits
Series and Parallel Circuits
In a series circuit, both bulbs are connected in a row, with electricity passing first through one then the other.
In the parallel circuit, electricity passes through both bulbs at the same time.
A major advantage of parallel circuits is that if one bulb malfunctions, the other bulbs continue to function.
In a series circuit, when one bulb breaks, both bulbs stop working.
