Electricity and Magnetism
Ch 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
2 uncharged object touch --> electrons move from 1 to the other
How Materials Affect Static Charging
When 1 material's electrons are attracted to another material more than they are attracted to their own
Charging by Induction
Induction
Charge Polarization
If electrons cannot easily move away from their atoms, the negative charges within the atoms shift to the side away from the object.
Technology uses static electricity.
1.2: Charges can move from one place to another.
Static charges have potential energy
Electric Potential Energy
The energy of a charged particle has due to its position in an electric field.
Electric Potential
Electric Potential
Volt
Charge Movement
When a charge moves, some of its electric potential energy is used in moving the charge and some is used to do other work.
Lightning
a high-energy static discharge
Materials affect charge movement
Conducters and Insulators

Ohms
Superconductors
Almost no resistance at very low temperature
