WHAT IS THE DIFFERENCE BETWEEN GENERATOR AND ALTERNATOR

Generator and Alternator.

Generator convert mechanical energy into electrical energy, Alternator also converts mechanical energy into electrical energy but there is the difference between both.

Generator and alternator are functionally same but the only difference in construction.  Generator persists stationary magnetic field and rotating conductor which rolls on the armature with slip rings and brushes.

Hence it converts the induced emf into dc current for external load whereas an alternator has a stationary armature and rotating magnetic field for high voltage and for low voltage it has vice versa.
