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 $L$?

Quoted from Wikipedia: Inductance:
It is customary to use the symbol $L$ for inductance, in honour of the physicist Heinrich Lenz.
