Frequently Asked Questions
-
What does nanohenry measure?
-
Nanohenry measures electrical inductance, representing an element's ability to store magnetic energy and resist changes in current, especially for very small inductances in RF engineering.
-
Where is the stathenry unit used?
-
Stathenry is used in the cgs-electrostatic (Gaussian/ESU) system, often for theoretical electrodynamics, plasma physics, and astrophysics, as well as in interpreting older scientific works.
-
Why is the conversion from nanohenry to stathenry important?
-
This conversion allows users to compare inductance values across SI and cgs unit systems, facilitating work with both modern engineering and classical physics contexts.
Key Terminology
-
Nanohenry (nH)
-
A unit of inductance equal to 10⁻⁹ henry, used to measure very small inductances in high-frequency and RF engineering.
-
Stathenry (stH)
-
The cgs-electrostatic unit of inductance where 1 stathenry induces 1 statvolt electromotive force under 1 statampere per second change of current.
-
Inductance
-
A property of an electrical element that stores magnetic energy and opposes changes in electrical current.
