Introduction to Galvanometers

The video introduces a galvanometer, an instrument that uses electromagnetism to measure small currents. It consists of a coil of wire around iron, connected to a needle, which moves in response to current flow. The video explains how the needle's movement correlates with current strength and highlights the galvanometer's role in devices like ohmmeters and voltmeters for measuring voltage in circuits.
