Electrical Power – Its Types and Units Introduction Electrical power is a fundamental concept that plays a pivotal role in modern society. From lighting our homes to powering vast industries, electrical power has become an indispensable part of our daily lives. In this article, we will explore what electrical power …

Answer: Motor rating in kilowatts (kW) represents real power, which is the actual power consumed for mechanical work. Kilovolt-amperes (kVA) would include both real power and reactive power, but for motors, the emphasis is on real power. Reasoning: Real Power vs. Apparent Power: Kilowatts (kW) represent real power, reflecting the …

Answer: Transformers are rated in kVA (kilo-volt-amperes) instead of kW (kilowatts) because kVA accounts for both real power (kW) and reactive power, which is essential for sizing and designing electrical systems. Reasoning: Transformers are devices used to transfer electrical energy between circuits. They handle both real power (expressed in kilowatts, …
