Question
he resistance of the field windings in the DC shunt machine is …….. its value in the DC series machines higher thanequal or less thanless thanequa
Solution 1
The resistance of the field windings in the DC shunt machine is higher than its value in the DC series machines.
Here's why:
-
In a DC shunt machine, the field windings are connected in parallel to the armature. This means that they must have a high resistance to limit the current flowing through them.
-
In contrast, in a DC series machine, the field windings are connected in series with the armature. This means that they must have a low resistance to allow a high current to flow through them.
-
Therefore, the resistance of the field windings in a DC shunt machine is higher than in a DC series machine.
Solution 2
The resistance of the field windings in the DC shunt machine is higher than its value in the DC series machines.
Here's why:
-
In a DC shunt machine, the field windings are connected in parallel to the armature. This means that they must have a high resistance to limit the current flowing through them.
-
In contrast, in a DC series machine, the field windings are connected in series with the armature. This means that they must have a low resistance to allow a high current to flow through them.
-
Therefore, the resistance of the field windings in a DC shunt machine is higher than in a DC series machine.
