Today during our morning comute I made a comment on how you can remember when, E, voltage leads, I, current in an, L, inductive or, C. capacitive circuit.

The phase to remember is, ELI the ICE man.

In an L inductive circuit; E leads I. (see how E leads L and I lags in the name ELI).

In a Capacitive circuit; I leads E.  (See how I leads C and E lags in the word ICE).

The phrase uses the same letters we use for Ohms law and math problems so the only thing to learn is the phase.
