Review electric field and electric charge. Discuss electric potential energy as energy formed moving a charged particle against an electric field and the electric potential as the electric potential energy/ charge, measured in volts. Discuss volts as being energy/coulomb. Use the flow of water and movement of heat energy to define movement from high to low pressure and energy. Relate both to the electric potential difference, or difference in voltage, which will cause charges to move from high to low potential difference. Define electric current as the flow of electric charge in a conductor, carried by electrons. Define amperes as the unit of current and that one ampere is one coulomb of charge/ sec. Discuss resistance to flow and that it depends on the thickness and length of wire, and that resistance reduces the current and converts some to heat energy. Write Ohms law, problems to be solved at the next meeting.
