Question

Please Any One.... Solve it...

consider a dc machine having its armature wound in lap fashion having 12 coils and each resistance 0.1 ohms. find the measured resistance between two adjacent commutator segments.

Answer 1

Answer:

0.092 ohms

Explanation:

Explanation: There are 11 resistance which are in parallel to one resistance. So taking the equivalent resistance of 11 series connected

resistance and the one single resistance of the commutator segment.

R(eq) = 0.1||1.1 = 0.0917
