The Ballistic Galvanometer is a highly sensitive electrical measuring instrument used to measure the quantity of electric charge passing through a circuit. Unlike conventional galvanometers that measure steady current, a ballistic galvanometer is specifically designed to detect and measure short-duration current pulses, making it an essential apparatus for physics laboratories, research institutions, and educational demonstrations.
The instrument operates on the principle that the first angular deflection of the moving coil is proportional to the total charge that flows through it. It is widely used in experiments involving capacitance measurement, magnetic flux determination, electromagnetic induction studies, and calibration of electrical instruments. Its high sensitivity enables accurate observation and measurement of very small quantities of charge.
