Ballistic galvanometer

A ballistic galvanometer is a type of sensitive galvanometer; commonly a mirror galvanometer. Unlike a current-measuring galvanometer, the moving part has a large moment of inertia, thus giving it a long oscillation period. It is really an integrator measuring the quantity of charge discharged through it. It can be either of the moving coil or moving magnet type. where K is expressed in coulombs per centimeter. In operation the unknown quantity of charge Q (in coulombs) is simply: .
