Consider the historical versus modern measurement context when using converted values
Frequently Asked Questions
-
What does one henry represent?
-
One henry is the inductance of a circuit where a change in current of one ampere per second induces an electromotive force of one volt, quantifying magnetic flux linkage per unit current.
-
Why convert henry to ESU of inductance?
-
Converting henry to ESU of inductance helps interpret legacy data, supports classical electromagnetic studies, and facilitates comparison between SI and cgs-ESU units.
-
Is ESU of inductance commonly used today?
-
No, ESU of inductance is a historical unit seldom used in modern engineering but remains important for historical research and education.
Key Terminology
-
Henry [H]
-
The SI unit of inductance representing magnetic flux linkage per unit current, defined by a circuit inducing one volt from a one ampere per second current change.
-
ESU of inductance
-
A historical unit of inductance from the electrostatic cgs-ESU system, used in pre-SI electromagnetic theory to describe electromotive force generation.
-
Inductance
-
A property of an electrical circuit that quantifies the ability to induce electromotive force due to changes in current.
