Question: A dc machine has 6 poles all connected in series. Each pole has 9 H inductance and field current is 2 A. Total inductance and total energy stored are
[A].

9 H and 18 J

[B].

18 H and 36 J

[C].

54 H and 108 J

[D].

108 H and 216 J

Answer: Option C

Explanation:

Total L = 6 x 9 = 54 H.

Energy = x 54 x 22 = 108 J.
