Galvanometer Experiment Procedures

This video tutorial guides viewers through determining the resistance of a galvanometer using the half deflection method and finding its figure of merit. It outlines the necessary electrical components, provides detailed instructions for setting up the circuit, and explains how to achieve full and half scale deflections on the galvanometer. The tutorial concludes with steps for recording observations and calculating the galvanometer's resistance.

What is the primary objective of the experiment discussed in the video?
