Q.

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

• ABe a cumulatively compounded generator but the interpole coil connection are to be reverse
• BBe a cumulatively compounded generator without reversing the interpole coil connections
• CBe a differentially compounded generator without reversing the interpole coil connection
• DBe a differentially compounded generator but the interpole coli connection are to be reversed
