So you've all heard of Henrys per metre, but just what exactly is a Henry?

Well, in the wonderful world of physics, the Henry (symbol H) is the SI unit for Inductance, which is a property of an electrical circuit measuring the induced voltage compared to the rate of change of the current in the circuit. The unit is named after Joseph Henry (1797-1878), an American scientist who discovered electromagnetic induction independently of and at about the same time as Michael Faraday (1791-1867). Below is the definition of a Henry, where,

H = Henry m = Metre

kg = Kilogram Wb = Weber

A = Ampere s = Second

Ω = Ohm J = Joule

V = Voltage C = Coulomb

So there you go kiddo's, till next time, Macracon out.
