Losses and efficiency of DC generator || condition for maximum efficiency of DC generator

 

in this video I will tell you
1. losses in DC Generator
2. efficiency of DC generator
3. condition for maximum efficiency of DC generator

question- a DC shunt generator is delivering 500 a at 220 volt the shunt field current is 10 a the armature resistance is 0.01 ohm the stray power is 5000 watt the efficiency of the gener
