soft question - Is there a historical name for an inductor that starts with the letter $L$? (RL circuits)



Why is a circuit with a resistor and inductor called an RL circuit and not an RI circuit?



Was there a now-obsolete name for an inductor that started with the letter $L$?



Answer



Quoted from Wikipedia: Inductance:



It is customary to use the symbol $L$ for inductance, in honour of the physicist Heinrich Lenz.
