A differentially compounded dc motor with interpoles and with brushes on the neutral axis is to be driven as a generator in the same direction with the same polarity of the terminal voltage. It will then
A. be a cumulatively compounded generator but the interpole coil connections are to be reversed.
B. be a cumulatively compounded generator without reversing the interpole coil connections.
C. be a differentially compounded generator without reversing the interpole coil connections.
D. be a differentially compounded generator but the interpole coil connections are to be reversed.
