The field supply also remains The alternator will:

The driving power from the prime-mover driving the alternator is lost but the alternator remains connected to the supply network; the field supply also remains The alternator will:

1. get burnt
2. behave as a synchronous motor but will rotate in a reverse direction to that corresponding to generator action
3. behave as an induction motor but will rotate in the opposite direction
4. behave as a synchronous motor and will rotate in the same direction
