The class will start with a classwork review sheet to review the previous days class. A circuit will be constructed using set of batteries to change voltage, a set of light bulb resistance to adjust resistance, thin wire, a voltmeter and an ammeter. The following relationships will be studied. The affect on current (amps) when the resistance is constant and the voltage increased and the effect on current when the voltage is constant but the resistance increased. A graph will be drawn of voltage vs current. The relationship will be expanded into Ohm's law. A few problems will be solved to determine the voltage or current or resistance when 1 of the parameters are changed
