QUESTION#01 A shunt-wound DC motor with the field coils and rotor connected in parallel (Figure 1) operates from a 125 V DC power line. The resistance of the field windings, Rr , is 226 0 . The resistance of the rotor, Rr, is 4.70 0 . When the motor is running, the rotor develops an emf &. The motor draws a current of 4.34 A from the line. Friction losses amount to 40.0 W . Compute the field current ly Express your answer in amperes. Compute the rotor current Ir Compute the omf E. Compute the rate of development of thermal energy in the field windings. Express your answer in watts. Compute the rate Putrotor of development of thermal energy in the rotor. Express your answer in watts. Compute the power input to the motor An Express your answer in watts. Compute the efficiency of the motor Express your answer as a decimal as opposed to a percentage
