Chapter 1: Electricity
1.1 Materials can become electrically charged.
Electric charge is a property of matter.
Electric charge
Electric Field
Static charges are caused by the movement of electrons.
Charging by contact
Static Charge
How materials affect static charging
Charging by contact can occur between two materials that come in contact with each other, where one gives electrons to the other.
Charging by Induction
Induction
Charge polarization
If electrons want to move away from their atom but can't, they can shift to a different part of the atom. When two things do this and attract each other they are "polarized".
Technology uses static electricity.
1.2 Charges can move from one place to another
Static charges have potential energy
Electric potential

Volt
Electric potential energy
Electricity doesn't get its potential energy from gravity, but its position in an electric field.
Lightning
Lightning is an extreme high energy discharge that happens between either multiple clouds or clouds and the ground.
Charge movement
Some of the power in a charge is used while it moves, and thus can only travel a certain distance dependent on the strength of the charge.
Materials affect charge movement.
Conductors and Insulators
conductor
insulator
Resistance
resistance
ohms
Superconductors
Some materials have almost no resistance, these materials are called superconductors. They have to be kept cold to work however.
Grounding
Electric current is a flow of charge.
Electric charge can flow continuously.
Current, Voltage, and Resistance
Ampere
Measuring electricity
Electric cells supply electric current
Electric cell
Electrochemical cells
Solar cells
