Q.
In a synchronous generator

AThe armature mmf leads the air gap flux and air gap flux leads the field mmf
BThe armature mm leads the air gap flux and the air gap flux lags behind the field mmf
CThe armature mmf lags behind the air gap flux and airgap flux lags behind the field mmf
DThe armature mmf lags behind the air gap and air gap flux leads the field mmf.

Correct Answer : (C)
The armature mmf lags behind the air gap flux and airgap flux lags behind the field mmf

Hints :

In a synchronous generator The armature mmf lags behind the air gap flux and airgap flux lags behind the field mmf.
