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.
Emu of Inductanceemu
Target UnitThe emu (abbreviated as 'emu') is a non-SI unit of electrical inductance that is equal to one henry. It is primarily used in the field of electromagnetism and is defined such that a current change of one ampere per second generates an electromotive force of one volt across the inductor. The emu is a part of the electromagnetic system of units (EMU) and is significant in theoretical and experimental physics, capturing the relationship between time-varying magnetic fields and induced currents.
Current Use
Today, the emu of inductance is primarily utilized in specialized fields such as theoretical physics, electrical engineering, and magnetics research. While most engineering applications favor the henry for its adherence to the SI system, the emu is still referenced in contexts involving historical calculations or in specific electromagnetic literature. It serves as a practical example of the electromagnetic unit system's legacy in contemporary scientific discussions.
Fun Fact
The emu is an example of a 'cgs' unit, which stands for 'centimeter-gram-second' system, highlighting its historical context.

inductance ā¢ SI Unit
Definition
The 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.
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.
