Thanks!A shunt generator supplies a load of 5,500 W at 110 V through a pair of feeder conductors having a resistance of 0.02 ohm each. The armature and shunt field resistances are 0.15 ohm and 50 ohms, respectively. Find the emf generated. (Write only the value without the unit) (Round-off to 2 decimal places) Round your answer to 2 decimal places.$ C₁ = [0.05P² + 20P₂ + 30] hr C₂ = [0.056P2 + 15P₂ + 40] hr Here P₁ and P₂ are in MW.
