Convert volt ampere to femtojoule/second
Please provide values below to convert volt ampere [V*A] to femtojoule/second [fJ/s], or Convert femtojoule/second to volt ampere.
How to Convert Volt Ampere to Femtojoule/second
1 V*A = 1e+15 fJ/s
Example: convert 15 V*A to fJ/s:
15 V*A = 15 × 1e+15 fJ/s = 1.5e+16 fJ/s

Volt Ampere
Volt ampere (V·A) is a unit of apparent power in an electrical circuit, representing the product of voltage and current without considering power factor.
History/Origin
The volt ampere was established as a unit of apparent power with the development of electrical engineering, particularly as a measure in alternating current (AC) systems. It is derived from the SI units volt (V) and ampere (A).
Current Use
Volt ampere is used to quantify apparent power in AC electrical systems, especially in the context of transformers, generators, and power supplies, to assess capacity and performance.
Femtojoule/second
A femtojoule per second (fJ/s) is a unit of power representing the rate of energy transfer of one femtojoule (10^-15 joules) per second.
History/Origin
The femtojoule/second unit emerged with the development of high-precision measurements in nanotechnology and quantum physics, where extremely small energy transfer rates are relevant. It is derived from the SI units of energy (joule) and time (second), with 'femto' denoting 10^-15.
Current Use
The femtojoule/second is used in scientific research to quantify very small power levels, particularly in fields like nanotechnology, quantum computing, and molecular physics, where energy transfer rates are extremely low.
