The volt-ampere (VA) is a unit of measurement used to express apparent power in an electrical circuit. It represents the product of voltage (in volts) and current (in amperes) in an AC (alternating current) system. Unlike watts, which measure real power, volt-amperes account for both active and reactive power, making them essential for understanding the performance of electrical systems.
The volt-ampere is standardized under the International System of Units (SI) and is widely recognized in electrical engineering. The symbol for volt-ampere is VA, and it is often used in conjunction with other units to describe the power capacity of electrical devices, such as transformers and generators.
The concept of apparent power, represented by the volt-ampere, emerged as electrical systems evolved in the late 19th century. As AC systems became prevalent, the need for a unit that could encompass both voltage and current became essential. The volt-ampere was introduced to provide a clear understanding of power in AC circuits, distinguishing it from direct current (DC) systems.
To calculate the apparent power in volt-amperes, simply multiply the voltage (V) by the current (I): [ \text{VA} = V \times I ] For example, if a circuit operates at 120 volts and draws 5 amperes, the apparent power would be: [ \text{VA} = 120 , V \times 5 , A = 600 , VA ]

The Joule per Second (J/s) is a unit of power that quantifies the rate at which energy is transferred or converted. This tool is essential for anyone looking to understand energy consumption, efficiency, and performance in various applications, from household appliances to industrial machinery. By utilizing our Joule per Second Converter, users can seamlessly convert power measurements into different units, enhancing their understanding of energy dynamics.
The Joule per Second (J/s), also known as a Watt (W), is defined as the amount of energy transferred or converted per second. This metric is crucial in fields such as physics, engineering, and energy management, where understanding power consumption is vital.
The Joule per Second is part of the International System of Units (SI), which standardizes measurements across scientific disciplines. This ensures that calculations and comparisons are consistent and reliable, making it easier for professionals and researchers to communicate their findings.
The concept of power measurement has evolved significantly since the early days of physics. The term "Watt" was named after James Watt, an 18th-century inventor who made significant contributions to the development of the steam engine. Over time, the Joule per Second has become the standard unit for measuring power, reflecting advancements in technology and energy efficiency.
To illustrate the use of Joules per Second, consider a light bulb that consumes 60 Watts. This means it uses 60 Joules of energy every second. If you want to calculate the total energy consumed over a period, simply multiply the power by the time in seconds. For example, in one hour (3600 seconds), the energy consumed would be: [ Energy (J) = Power (W) \times Time (s) = 60 , W \times 3600 , s = 216,000 , J ]
Understanding Joules per Second is crucial for various applications, including:
To use the Joule per Second converter:
What is Joule per Second (J/s)? Joule per Second (J/s) is a unit of power that measures the rate of energy transfer or conversion, equivalent to one Watt (W).
