Volt-ampere - Wikipedia
The volt-ampere (SI symbol: VA, [1] sometimes V⋅A or V A) is the unit of measurement for apparent power in an electrical circuit. It is the product of the root mean square voltage (in volts) and the root mean square current (in amperes). [2] Volt-amperes are usually used for analyzing alternating current (AC) circuits.
What is a volt-ampere (VA) and how does it work? - TechTarget
A volt-ampere (VA) is a measurement of power in a direct current electrical circuit. The VA specification is also used in alternating current (AC) circuits, but in this case, it represents apparent power (represented in VA), which often differs from true power (represented in watts).
What’s The Difference Between Watts And Volt-Amperes?
2012年5月2日 · Both watts (W) and volt-amperes (VA) are units of measurement for electrical power. Watts refer to “real power,” while volt-amperes refer to “apparent power.”
Volt-ampere - Simple English Wikipedia, the free encyclopedia
A volt-ampere is the measurement of power in a direct current. In a DC circuit, 1 VA is the equivalent of 1 W. This equivalence means that the power factor of that power supply is 1.
What is the difference between watts and volt-amperes?
2019年2月20日 · Watts refer to “real power,” while volt-amperes refer to “apparent power.” Both are simply the product of voltage (V) multiplied by amperage (A). Thus, a device drawing 3 amps at 120 volts would be rated at 360 watts or 360 volt-amperes.
What’s the Difference Between Amps, Volts, and Watts? - Bob Vila
2024年4月5日 · The volt-ampere describes apparent power in an electric circuit, while wattage measures real power.

Volt-Ampere | Analog Devices
A volt-ampere (VA) is the voltage times the current feeding an electrical load. A kilovolt-ampere (kVA) is 1000 volt-amperes. Electrical power is measured in watts (W): The voltage times the current measured each instant.
Difference between Voltage and Ampere (Volts vs Amp)
The main difference between Volts and Ampere (volts vs Amp) is that the volt is the SI unit of measuring the Potential difference between two points, Voltage, and EMF (Electromotive force) Whereas Ampere or Amp is the SI unit of measuring current flowing in the circuit.
Difference between volts and amps | Volts vs amps - Electrical …
Volts and amps or ampere are two measures of electricity. Specifically, voltage is the measure of electric potential difference between two points whereas ampere is the measure of electric current. They are closely related terms and can be a bit difficult to understand.
