HiAn instrument used to detect small amounts of electric charge or current is called a galvanometer or an electroscope, depending on how you apply it. Galvanometer: A sensitive device used to detect and measure small electric currents. It works on the principle of electromagnetic deflection. Electroscope: A simple device used to detect the presence of electric charge. It operates based on electrostatic repulsion between charged leaves.
