Q1:

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

ANS:C - 54 H and 108 J

Total L = 6 x 9 = 54 H. Energy = x 54 x 22 = 108 J.
