Measurement of Low Resistance by Carey Foster's Bridge experiment

In this Physics practical video, we will perform the Carey Foster’s Bridge experiment to measure low resistance accurately. The procedure includes two main parts: 1.Determination of the resistance per unit length of the Carey Foster’s bridge wire 2.Measurement of an unknown low resistance This practical works on the principle of Wheatstone’s bridge and is widely used for precise resistance measurement. The video explains the complete setup, readings, calculations, and final result, making it helpful for practical file preparation. This is an important core experiment in BSc Physics. You will learn step by step how the Carey Foster’s bridge reduces error in measuring small resistances and how to practically find the resistance of a given wire or coil.
