The correct answer is 0.092 ohms.
Explanation:
- According to the given values in the question, there are around 11 numbers of resistances in the DC machine.
- DC refers to Direct Current.
- The 11 resistances are found in series.
- These refer to equivalent resistance.
- While 1 resistance is found in the commutator segment.
- The formula used for this is R(eq) = 0.1||1.1 = 0.0917.
