A classwork review sheet will be first used as a review. Using a setup consisting of batteries and holders, a voltmeter, an ammeter, wire connectors, and low voltage bulbs, the principles of Ohms law will be shown. The direct relationship of voltage to current was shown with resistance being constant. As the voltage increases, the current increases in a direct proportion. Resistance was now varied with voltage remaining the same, showing the inverse relationship between current and resistance. Ohms law formula was derived and a few examples to solve for unknowns given.
