why transformers use kVA and not kW

The video tutorial explains how transformers transfer power using Volt amps, as the kilowatts depend on the connected device. It introduces the concept of power factor, which is the ratio of true power to apparent power, and uses a beer analogy to illustrate the difference between true power (useful) and reactive power (wasted). The tutorial concludes by discussing how transformer capacity is determined and how device efficiency affects power usage.
