Answer: A
Share your understanding of this question with the correct explanation.
The inter-pole in a DC machine is connected in series with the field winding.
Inter-poles, also known as commutating poles, are additional poles placed in between the main poles of a DC machine. They are designed to improve the commutation process and reduce sparking at the brushes by neutralizing the armature reaction. Inter-poles produce a flux that opposes the armature reaction, helping to maintain the commutation process.
To achieve this, the inter-pole winding is connected in series with the field winding. This means that the current flowing through the field winding also passes through the inter-pole winding, allowing the inter-poles to contribute to the overall magnetic field produced by the machine.
Therefore, option A, “Series,” is the correct answer.
