=  250  = 5 A
                            50
       Load current IL   =  Ia - Ish

       Armature voltage, Ia  =  IL +  Ish
                     
                       = 500 + 5

                       = 505A

          Armature voltage, Va  =  IaRa

                         = 505 x 0.06
                     = 30.3V
:. Generated emf = terminal voltage + amature voltage
                             = 250 + 30.3
                         =280.3V
This question was on direct current machine. This question was popular. The candidates' performance was fair.

Many candidates drew a labelled circuit but could not properly appropriate     formulae to Compute the required quantities under application.
