Question

10- A 250 kW, 230 volt compound generator is delivering 800 amps. at 230 volts the shunt field currents is 12 amp the armature resistance is 0.007 ohm and the series field resistance is 0.002 ohm the stray power at this load is 5500 watts the generator is connected long compound determine generator efficiency at this load 11-A certain 110-volt shunt generator has an armature and brush resistance of 0.06 ohm at full load of 85 amperes the resistance of the shunt field is 45 ohms and the stray power losses are found to be 897 watts calculate the full load efficiency of the generator

          10- A 250 kW, 230 volt compound generator is delivering 800 amps. at 230 volts
the shunt field currents is 12 amp the armature resistance is 0.007 ohm and the
series field resistance is 0.002 ohm the stray power at this load is 5500 watts the
generator is connected long compound determine generator efficiency at this
load

11-A certain 110-volt shunt generator has an armature and brush resistance of 0.06
ohm at full load of 85 amperes the resistance of the shunt field is 45 ohms and
the stray power losses are found to be 897 watts calculate the full load
efficiency of the generator
