ballistic galvanometer

A ballistic galvanometer is a type of instrument used to measure the quantity of electric charge passing through a circuit. It works on the principle of electromagnetic induction, where the movement of a coil in a magnetic field generates a current proportional to the charge. The ballistic galvanometer is unique in that it is able to measure the total charge of a pulse rather than the rate of flow of charge, making it useful in applications such as studying the behavior of capacitors or in ballistic measurements. By utilizing the principles of electromagnetism, the ballistic galvanometer provides a reliable and accurate means of measuring electric charge in a variety of settings.
