Share:
- 1The armature current drawn from the supply mains is maximum at unity power factor for a given mechanical load.✓
- 2A synchronous motor operates at a leading power factor when it is in an overexcited condition.
- 3If the mechanical load on a synchronous motor operating at unity power factor is increased while keeping excitation constant, its power factor becomes lagging.
- 4With the reduction of DC excitation below normal, a synchronous motor draws lagging current from the supply mains.
Correct answer
The armature current drawn from the supply mains is maximum at unity power factor for a given mechanical load.
