True. A galvanometer works on the principle of conversion of mechanical energy into electrical energy.
Explanation:
Galvanometer works on the principle of converting electrical energy into mechanical energy. When a current flows through a magnetic field, a magnetic torque is experienced. It rotates at an angle equal to the current flowing under a regulating torque. The moving coil galvanometer is a highly sensitive instrument that can be used to detect the presence of current in any given circuit. If the galvanometer is connected to the Wheatstone bridge circuit, the pointer in the galvanometer shows zero deflection, i.e. no current flows through the device. The pointer deflects to the left or to the right, depending on the direction of the current.
