In electrical terms, what does ELI indicate?

Explanation:
ELI means the voltage across an inductor leads the current by 90 degrees. In an inductor, the voltage is tied to the rate of change of current, so V_L = L di/dt, which places voltage ahead of current in phase. In phasor form, V = jωL I, showing the voltage leading the current. This mnemonic doesn’t describe capacitors (where current leads voltage) or specify an inductive reactance value (X_L = ωL); it’s about the relative timing of voltage and current in inductors.
