Plss help.?

A 240V shunt DC motor draw a current of 3.5A on no load. the ammature circuit resistance is 0.4ohm and shunt field winding resistance is 160ohm. When the motor operates at full load at 2400 rpm it draws 24A. a) its efficiency at full load b) torque develope and useful torque c) the no load speed d) percent speed... show more A 240V shunt DC motor draw a current of 3.5A on no load. the ammature circuit resistance is 0.4ohm and shunt field winding resistance is 160ohm.
