A domestic load of 2300 kW at 0.88 p.f lagging and a motors load of 3400 kW at 0.85 p.f lagging are
supplied by two alternators operating in parallel. If one alternator is delivering a load of 3300 kW at 0.9 p.f
lagging, what will be the output power and p.f of the other alternator?
Design a bank of capacitors to provide 60V and 2kWh energy to capture and store regen breaking energy. Use commercial supercapacitor cells at 3V and 3600F.
Capacitor voltage drops almost linearly during discharge and below half voltage maximum it doesn’t provide significant power. If we discharge a fully charged capacitor to its half voltage maximum, how much energy can be discharged compared to a full-discharged capacitor (show your calculation)?
