# Is there a historical name for an inductor that starts with the letter $L$? (RL circuits) [closed]

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 $$L$$?

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