During a slip test, the field winding of a synchronous machine should be kept open to prevent excessive currents that could damage the windings or other components. An open field winding ensures that only the rotor's slip and associated losses are measured without introducing additional variables from the field excitation. This allows for accurate assessment of the machine's performance under slip conditions, reflecting true operational characteristics.
What else can I help you with?
Why field winding work as stator and armature winding as rotor?
No, these can be switched depending on the requirements of the application. It is more practical to have the armature windings (since they will carry the full load current) as the stator for this will require larger wires and is also easier to cool if kept stationary. The field windings do not carry the full load current of the load so this requires smaller wires and smaller slip rings since this is the piece that will rotate.
Why does the current carrying conductor experiences a force when it is placed in magnetic field state Fleming's left hand rule?
The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@ So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction. Ok now why does a force exist on the current carrying conductor? As current flows through a conductor magnetic lines are formed aroung the conductor. This magnetic field gets interaction with the external field and so a force comes into the scene.
What will happen if the armature rheostat is zero and field circuit resistance is kept high in a dc motor?
If the armature rheostat is set to zero and the field circuit resistance is kept high in a DC motor, the armature will receive maximum current, leading to a high armature current. However, with a high field circuit resistance, the field current will be low, resulting in a weak magnetic field. This imbalance can cause the motor to run at a very high speed, potentially leading to instability or damage due to excessive armature current and insufficient torque production. Overall, the motor may operate inefficiently and could risk mechanical failure.
How much intensity should be kept for CRO?
It depends on you... there is no such rule to keep intensity at a perticular point...
Does a current carrying conductor experience a force when kept parallel to the magnetic field?
Yes. The force attracts the conductor to the magnetic field, F= eVB = e(-V.B + VxB) = e[-V.B, ] =- eV.B when V and B are parallel!

They are usually kept in a stable with access to a field.
Where should a pen drive be kept while traveling to the USA?
A pen drive should be kept in your carry-on luggage while traveling to the USA to ensure it is easily accessible and secure during the journey.
Should you fertilize perennials and tropical plants kept in a greenhouse in Texas during the winter or do they need to be dormant during that time?

How often should grass be mowed to maintain a healthy and well-kept lawn?
Grass should be mowed regularly, about once a week during the growing season, to maintain a healthy and well-kept lawn.
Positive points for debate about animals should be kept in cages?
One of the positive points for debate about why animals should be kept in cages could be when they are being trained. Puppies are often kept kenneled during training. Another could be to keep them safe when no one is there to watch them.
How often do you have to cut grass to maintain a well-kept lawn?
To maintain a well-kept lawn, you should cut the grass about once a week during the growing season.
Can you lay down a water heater during installation?
No, you should not lay down a water heater during installation. It should be kept in an upright position to prevent damage and ensure proper functioning.
What happens if field mice get into a guinea pig cage?
Guinea pigs should be kept in a moderate temparature preferrably indoors. This should prevent field mice from getting into the cage. If you have any trouble you can always buy a new cage and set it up indoors.
What was the objective during the War Between the States?
it was be cuz they were fighting over if slaves should be kept or be set free
A place were horses are kept?
A field, a stable or a yard.
