Electrical Machines A 240 V, dc shunt motor draws 15 A while supplying the rated load at a speed of 80 rad/s. The armature resistance is 0.5 W and the field winding resistance is 80 W. The net voltage across the armature resistance at the time of plugging will be 6 V 234 V 474 V 240 V 6 V 234 V 474 V 240 V ANSWER DOWNLOAD EXAMIANS APP
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 somewhat less than 220 V 6 V 220 V more than 220 V somewhat less than 220 V 6 V 220 V ANSWER DOWNLOAD EXAMIANS APP
