6.1 Why learn about electricity?
We use it everyday. (We have to pay for it!)
It can be very powerful.
It can be dangerous.

6.1 Electric Circuits
An electric circuit is something that provides a path through which electricity travels.
The wires, switches, and motors are connected in electric circuits.

6.1 Electric Circuits
People’s first experience with electricity was in the natural world.
Examples:— The wiring that lights your house is an electric
circuit.— The nerves in your body create electric circuits.— Lightning, clouds, and the planet Earth form an
electric circuit.— The car battery, ignition switch, and starter form an
electric circuit.

6.2 The Coulomb and the Atom
The unit of electric charge is the coulomb (C).
Electrons in atoms stay close to the protons because they are attracted to each other.
