Electrical Machines A short-shunt cumulatively-compounded dc generator builds up a voltage of 220 V at no load at rated speed. If it is operated as a differentially compounded generator, other things remaining the same, it would build up more than 220 V 220 V 6 V somewhat less than 220 V more than 220 V 220 V 6 V somewhat less than 220 V ANSWER DOWNLOAD EXAMIANS APP
