Demonstrate the relationship between voltage, current, and resistance using this kit and a Genecon as a power source. Students will gain a better understanding of Ohm's Law as they alter positions of clip leads along a nichrome wire and observe changes in the brightness of the attached bulb. This qualitative approach can be made more quantitative by adding an ammeter and voltmeter to the circuit. The kit consists of a 500 mm nichrome wire mounted on a wood base, a bulb, a socket, and alligator clip leads.
