1	Electricity Electricity – An energy source
2	Michael Faraday 1821 experimented with electromagnetism and developed the electric motor. In 1831 Faraday discovered the induction of electric currents.
3	Thomas Edison . He not only invented the first successful electric light bulb, but also set up the first electrical power distribution company. Edison invented the phonograph, and made improvements to the telegraph, telephone and motion picture technology.
4	Benjamin Franklin In the early 1750's he turned to the study of electricity. His observations, including his kite experiment which verified the nature of electricity and lightning brought Franklin international fame.
5	Which items are insulators? Insulators are materials that do not conduct electricity very well.
6	Which items are conductors? Conductors are materials that let electrical energy move through them.
7	Parallel Circuits There are 2 or more pathways for the current in a parallel circuit
8	Series Circuit There is only 1 pathway for the current.
9	Electric Current A continuous flow of negative charges or ELECTRONS creates an electric current.
10	Circuit A circuit is a pathway taken by an electric current.
11	Closed Circuit Allows the movement of electrical energy
12	Open Circuits Stops the movement of electrical energy
13	Lightning This is the discharge of static electricity in the atmosphere
14	Static Electricity Rubbing materials together creates static electricity Static means “not moving” so the negative charge stays on the object
15	Electrical Energy Can be transformed into: Heat Light Mechanical Energy
16	Electricity and Magnetism An electric current creates a magnetic field. A moving magnetic field creates an electric current.
17	Magnetic Fields Lines of force extend from the poles of a magnet in an arched pattern defining the area over which magnetic force is exerted.
18	Metallic Attraction Certain iron-bearing metals attract other such metals.
19	Electromagnets Wrapping a wire around certain iron-bearing metals like a nail creates a closed circuit and is an example of a simple electromagnet.
20	Review Questions Why was Thomas Edison important? Name 3 things that are insulators. List 3 things that are conductors. What is the difference between an open and closed circuit? What is the difference between a series and a parallel circuit? What type of metal attracts other metals?
