DIODE: A "A technique valve" for electrical energy. Diodes have small resistance in one direction, and infinite resistance in the other.
The rotor's magnetic field can be produced by permanent magnets, or by a field coil electromagnet. Automotive alternators make use of a rotor winding which lets control of the alternator's produced voltage by various The existing from the rotor subject winding. Long-lasting magnet devices avoid the decline on account of magnetizing latest within the rotor, but are limited in size, as a consequence of the price of the magnet substance.
