fJ/s to VA

femtojoule per second

• Definition: Femtojoule per second (fJ/s) is a unit of power that represents the rate at which energy is used or produced. It is equivalent to one quadrillionth of a joule per second.

• Symbol: The symbol for femtojoule per second is fJ/s.

• Usage: This unit is often used in fields that require precise measurements of energy transfer, such as nanotechnology and quantum computing.

volt ampere

• Definition: Volt ampere (VA) is a unit of apparent power in an electrical circuit, representing the product of voltage and current. It reflects the total power flowing in the circuit regardless of phase angle.

• Symbol: The symbol for volt ampere is VA.

• Usage: Volt amperes are commonly used in electrical engineering to describe the capacity of electrical equipment, especially in AC circuits.

Origin of the femtojoule per second

• The term “femto” originates from the Danish word “femten,” meaning fifteen, referring to the factor of 10^-15. The joule is named after the English physicist James Prescott Joule, who contributed significantly to the study of energy and thermodynamics. Femtojoules per second represent extremely small quantities of energy flow, making it suitable for modern applications.

Origin of the volt ampere

• The volt ampere unit combines the names of two pivotal figures in electrical engineering: Alessandro Volta and André-Marie Ampère. Volta is known for his work on electric potential and batteries, while Ampère is recognized for his contributions to electromagnetism. Together, the volt ampere quantifies electrical power, which is essential for understanding circuit performance.
