n. a very small unit for measuring inductance. It is equal to one billionth of a henry.
n. a unit of inductance equal to one billionth of a henry. It is the CGS unit of inductance and is now largely replaced by the SI unit.
The coil has an inductance of one abhenry.
In older physics textbooks, you might find the abhenry used to describe the inductance of tiny laboratory components.
While the henry is the standard SI unit for inductance, the abhenry remains a historical reference point for those studying the evolution of electromagnetic theory in the late nineteenth century.
