What does L stand for in ELI?

Explanation:
L in the ELI mnemonic points to inductance—the inductor’s property. The idea behind the mnemonic is to remember how voltage and current relate for inductors versus capacitors: in an inductor, voltage leads current, while in a capacitor, current leads voltage. The symbol L in circuit equations stands for inductance (measured in henries). The inductor’s impedance is Z = jωL, and the inductive reactance is X_L = ωL, both derived from that inductance. So L stands for inductance, not inductive reactance. The other options don’t fit the standard meaning.
