A 2-pole DC shunt generator charges a 100 V battery of negligible internal resistance. The armature of the machine is made up of 1000 conductors each of 2 mΩ resistance. The charging currents are found to be 10 A and 20 A for generator speed 1055 and 1105 rpm respectively. Find the field-circuit resistance (in Ω).
Enter numerical value using the virtual keypad. Round off where necessary.
