Apparent power is a term that is commonly used in the field of electrical engineering. It refers to the total amount of power that is being transferred between a source and a load, including both the real power and the reactive power. Understanding the concept of apparent power is essential for anyone who works with electrical systems, as it can help to ensure that power is being transferred efficiently and safely.
Definitions
Apparent power can be defined as the product of the voltage and the current in an AC circuit. It is measured in units of volt-amperes (VA) or kilovolt-amperes (kVA). Another definition of apparent power is the total power that is being transferred between a source and a load, including both the real power and the reactive power.
Origin
The term apparent power has its origins in the field of electrical engineering. It was first used in the early 20th century to describe the total power that is being transferred between a source and a load in an AC circuit.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, apparent power is defined as “the product of the voltage and current in an alternating-current circuit, expressed in volt-amperes.” The Oxford English Dictionary defines it as “the total power in an electrical circuit, including both real power and reactive power.”
Associations
Apparent power is closely associated with real power and reactive power. Real power is the power that is actually being used by the load, while reactive power is the power that is stored and released by the circuit’s inductors and capacitors.
Synonyms
Some synonyms of apparent power include total power, complex power, and volt-ampere.
Antonyms
There are no direct antonyms of apparent power, but it can be contrasted with real power and reactive power.
