Answer:
A galvanometer is an electromechanical instrument that is used for the detection of electric currents through electric circuits. It is a sensitive instrument and cannot be used for the measurement of heavy currents. It works on the principle of conversion of electrical energy into mechanical energy when a current flows in a magnetic field it experiences a magnetic torque and thus rotates through an angle proportional to the current flowing through it.
