Resistors and Ohm’s Law

How is resistance measured? Ohm's law I = V/R is the fundamental relationship between current, voltage, and resistance in a circuit. Devices that measure resistance are based on Ohm's law. These devices apply a known voltage and/or current, and then determine the resistance. In this investigation you will use a similar experimental technique to measure the resistance of a bulb.
