Galvanometer a power meter. Contains a coil that rotates around an axis placed Knight magnetic field. When an electric current through the coil to the moment of coupling torque coils to rotate. Do the pointer (with the rotation axis of the coil), according to Ben. Ben corner of pointer translations conjugate match the size of the electric current through the coil and torque back of spiral springs do the pointer stops at the corner. While an electric current through the coil. And thus pointer back to the starting position while no electric current through the coil to create scale by the pointer to match the current size of the
DC motor. The mechanical energy is transformed Contains a coil that rotates around an axis placed in a magnetic field coils and brush touch allows continuous rotation in one direction when a current from the battery through the coil.
