Measurement of Resistance Using Wheatstone Bridge Aim

This document describes how to measure an unknown resistance using a Wheatstone bridge. The Wheatstone bridge circuit is constructed using resistors, an unknown resistance, a multimeter, and connecting wires. The formula for calculating the unknown resistance is provided as Rx = (P/Q) * S, where P and Q are the potential divider ratios and S is the variable resistance arm. The procedure involves adjusting the Wheatstone bridge to a balanced condition by varying S and then calculating Rx using the measured ratio and resistor values.
