2-b A DC machine operates as a motor. The machine is connected as a short shunt motor, with a brushvoltage drop of 2 volts. The armature resistance is 0.20 Ω, the series field winding resistance is 0.1 Ω andthe shunt field winding resistance is 200 Ω.The input voltage is 210 V and the input current is 50 amps. The rotational losses are 100 watts. Determine:b) The net output power, the power at the motor shaft in watts., Enter the answer in watts, i.e., 1.8 KW enter your answer as 1800
