Meaning and Definition
A unit of electrical inductance in the International System of Units (SI), equivalent to the inductance of a closed circuit in which an electromotive force of one volt is produced by an electric current varying at one ampere per second.
Capitalised as a proper noun (Henry), it is a common masculine given name; in lower case, it is used metaphorically in technical jargon to refer to a unit or a standard (e.g., 'a few henrys of inductance'). The plural is 'henrys' or 'henries'.

Frequency
Extremely low frequency in general discourse. Its occurrence is almost entirely confined to textbooks, research papers, and technical manuals in electrical engineering and physics.
