On the other hand, kVA is the apparent power, which includes both real power (kW) and reactive power (kVA). The relationship between kW and kVA is defined by the power factor (PF), which is the ratio of real power to apparent power (kW/kVA). A higher power factor indicates more efficient energy usage. For example, if a device has a power factor of 0.8, it means 80% of the apparent power is being converted into useful work. Understanding this distinction is crucial for designing efficient electrical systems and avoiding overloading circuits.
