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.
AbhenryaH
Target UnitThe abhenry (symbol: aH) is a unit of inductance in the centimeter-gram-second (CGS) system of units. It is defined as the inductance in a circuit when a current change of one abampere per second induces an electromotive force (emf) of one abvolt. One abhenry is equivalent to 10^-9 henries, the standard SI unit of inductance. Inductance is a measure of the ability of a coil to store energy in a magnetic field when an electric current flows through it. The abhenry is particularly useful in the realm of electromagnetic theory and applications, especially within the context of circuit analysis in systems utilizing CGS units.
Current Use
The abhenry is primarily of historical significance today, as the SI unit henry has become the standard in modern electrical engineering and physics. However, it is still referenced in specialized literature and discussions concerning historical measurements and concepts in electromagnetism. Certain academic papers and educational resources may use both CGS units and the SI system interchangeably for illustrative purposes, especially when dealing with topics that predate the SI system. In educational contexts, students in physics and electrical engineering may encounter the abhenry when studying the evolution of electrical units and their applications in circuit theory and design. Countries with strong historical ties to the CGS system, such as the United States, may still include discussions of the abhenry in their engineering curricula.
Fun Fact
The abhenry is one of the lesser-known units of inductance and is often overshadowed by the henry.

In practical terms, inductance is crucial for the functioning of various electrical and electronic devices, influencing their performance and efficiency.
History & Origin
The unit 'henry' was officially adopted in 1861 during the establishment of the International System of Units (SI). It was named in honor of Joseph Henry, an American scientist who made significant contributions to the understanding of electromagnetism and induction. Henry's pioneering work laid the foundations for many modern electrical technologies and his discoveries regarding self-induction and mutual induction were crucial in the development of the field. His experiments demonstrated how a change in current could induce a magnetic field, which formed the basis for the concept of inductance that the henry quantifies.
Etymology: The term 'henry' is derived from the name of Joseph Henry, reflecting the honor bestowed upon him for his groundbreaking contributions to electromagnetism.

The abhenry is particularly useful in the realm of electromagnetic theory and applications, especially within the context of circuit analysis in systems utilizing CGS units.
History & Origin
The abhenry was developed in the early 20th century as a part of the centimeter-gram-second (CGS) system of units. This system was particularly popular in the scientific community before the widespread adoption of the International System of Units (SI). The CGS system allowed for simpler calculations in electromagnetism and mechanics, which were heavily reliant on smaller units. The need for a practical unit of inductance arose as electrical engineering evolved and applications required precise measurements of inductance. In this context, the abhenry was defined to facilitate the study of electromagnetic phenomena and circuit designs.
Etymology: The term 'abhenry' is derived from the name of the American scientist Joseph Henry, who made significant contributions to the field of electromagnetism, particularly in the study of inductance and self-induction.
