Safety	Static Electricity	Current Electricity	Series & Parallel Circuits	Production of Electricity

Introduction     Electricity is widely and commonly used, and yet, many do not understand how it works. This unit is one of the more practical units you will deal with in grade 9.     I have included a list of major concepts, some detail you should be familiar with and some links to numerous sites which will allow you to view, download or print material which is directly related to these concepts. In addition there may be some material which is of interest to you (hey you never know!). The links will assist you if you run into any difficulties and have specific questions. Major Concepts: Safety Identify some unsafe practises What to do if....... Static Electricity Law of electric charges. Electrical nature of matter Ways to statically charge (friction, contact, induction) Ways to discharge (grounding and at a point) Insulators and conductors Industrial uses Current Electricity Current, potential difference and resistence. Ohm's law. Shock Series and Parallel Circuits Circuit (load, source, connector, control device). Differences Percent effeciency Production of Electricity Various methods of producing electricity.
