Unit Explanations
HenryH
Source UnitThe henry (H) is the SI unit of inductance, which quantifies the ability of a conductor to store energy in a magnetic field when an electric current flows through it. Specifically, one henry is defined as the inductance of a circuit in which a change in current of one ampere per second induces an electromotive force of one volt. This definition underscores the relationship between current, voltage, and inductance, which is critical in understanding electromagnetic phenomena. The henry serves as a fundamental unit in electrical engineering and physics, particularly in the study of circuits, transformers, and inductors. In practical terms, inductance is crucial for the functioning of various electrical and electronic devices, influencing their performance and efficiency.
Current Use
The henry is widely used in various industries including electronics, electrical engineering, and telecommunications. In electrical engineering, inductorsācomponents that store energy in magnetic fieldsāare characterized in henries. Devices such as transformers, motors, and generators utilize inductance to function efficiently, making the henry a vital metric in their design and operation. In telecommunications, inductors are used in filters and oscillators to manage signal integrity and frequency response, highlighting the henry's relevance in modern communication systems. Additionally, in the automotive industry, inductance measurements are crucial in the development of electric vehicles, hybrid systems, and advanced driver-assistance systems (ADAS). The henry's application extends globally, with countries such as the United States, members of the European Union, and Japan all employing it in their engineering standards and practices.
Fun Fact
The henry is one of the seven base SI units, underpinning many areas of electrical engineering.
AttohenryaH
Target UnitThe attohenry (symbol: aH) is a sub-unit of inductance, derived from the SI unit henry. One attohenry is defined as one quintillionth of a henry (10^-18 H). Inductance, a fundamental property of electrical circuits, signifies the ability of a conductor to induce an electromotive force (EMF) due to a change in current. This property is critical in the functioning of inductors, transformers, and in many electronic circuits. The extremely small value of attohenry indicates its use in applications involving very low levels of inductance, such as in microelectronics and advanced physics experiments where small inductive effects are measured. The unit denotes precision in measurements and is crucial for cutting-edge technology.
Current Use
The attohenry is primarily utilized in fields requiring high precision measurements of inductance, particularly in microelectronics and nanotechnology. Industries such as telecommunications, semiconductor manufacturing, and quantum computing often deal with components exhibiting inductance at the attohenry scale. For instance, the design of integrated circuits may require inductance values measured in attohenries to ensure the functionality of components at micro and nanoscales. Countries with advanced technology sectors, including the United States, Japan, Germany, and South Korea, extensively use the attohenry in research and development. Specific applications include the development of ultra-fine inductors used in RF circuits and other high-frequency applications. The attohenry facilitates precision in inductive measurements that contribute to enhancements in device performance and efficiency.

History & Origin
The concept of inductance was introduced in the late 19th century with the foundational work of physicists like Michael Faraday and Joseph Henry. Faraday's law of electromagnetic induction laid the groundwork for understanding how inductance works, while Henry contributed to the quantification of inductance as a measurable property. The term 'henry' was adopted as a unit in 1861 to honor Joseph Henry's contributions to the field. The prefix 'atto-' was established later, in the 1960s, as part of the International System of Units (SI) to facilitate the expression of very small quantities, such as inductance at extremely low scales.
Etymology: 'Atto' is derived from the Danish word 'atten,' meaning 'eighteen,' which represents the factor of 10^-18, while 'henry' is named after the American scientist Joseph Henry.
