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. READ MORE AR Vol 90 No 6 2022
