Unit zH
Name zeptohenry
Category Inductance
Details A zeptohenry (zH) is a unit of inductance in the International System of Units (SI) representing 10^-21 henrys, which is an extremely small unit of inductance. The unit is named after the German physicist Joseph Henry, who discovered the phenomenon of magnetic inductance in the early 19th century.

Inductance is a property of electrical circuits that indicates the ability to store energy in a magnetic field when current flows through a conductor, such as an inductor or a wire coil. The unit zeptohenry is typically used to describe very tiny or nano-scale inductors in nanotechnology, high-frequency electronics, and other applications where such small inductances are required.
