Q. Power transformers are rated in which of the following measures? kilovolt-amperes None of the given options kilowatt-volts kilowatts

The correct answer is **kilovolt-amperes (kVA)**.Power transformers are rated in kilovolt-amperes (kVA) because this rating reflects the apparent power, which is the combination of real power (kilowatts, kW) and reactive power (kilovars, kVAR). Kilowatts only represent the real power consumed by the load, while the transformer also handles reactive power associated with inductive loads. The kVA rating indicates the transformer's capacity to handle both real and reactive power.
