Resonant Circuits |
 |
An important element of any radio communications equipment is the LC
circuit. L is the inductance measured in Henries (H) and named after
Joseph Henry (1797–1878). The symbol L for inductance was chosen to
honour Heinrich Lenz (1804-1865) who pioneered work in
electromagnetic induction. |
