fundamental unit of charge

• Coloumb

• 1.6x10^-19

• -1.6x10^-19

• small discrete unit of charge that can exist.

• the charge on an electron or proton

SI unit of charge

• C

• A x s

• J

• V/A

what is an insulator

• molecules with electrons that are closely linked to the nuclei

• any material that will not easily distribute a charge over its surface

• metals

• nonmetals

what is a conductor

• any material that distributes charge over its surface and transfers charges well

• metals

• nonmetals

• electrons move easily and aren't as closely associated with the nucleus

what is an electrical field

• any given charged particle will create a field that radiates outward or inward in all directions

• charged particles that enter the electric field of a different object are liable to experience electrostatic forces

• the charge creating an field of interest

• any given charged particle that will create a field that radiates outward or inward in one direction

an electric fields positive charge radiates

a negative charge's electric field radiates

the stronger the electrical field is
