In shunt DC generator, the rated load power and speed are 6kW and 1500rpm. The rated load voltage is 230V. The internal armature resistance is 0.920. The resistance of the field winding is 1770. Calculate the following: (a) The no -load voltage (b) Electromagnetic torque needed to start the generator armature in N-m Hint: Use the formula Pin = (27t N T) / 60 where PIn is the power input N is the generator rated sped in rpm Tis the torque needed to crank the generator armature in N-m (c) The percentage voltage regulator
