Can explain when current/voltage lead and lag in capacitor and inductor.

The current lags behind the voltage by 90 degree. Phase angle (if the circuit is pure inductive, otherwise the angle depends on the value of inductance).

Voltage leads current by 90 degrees in pure inductance.
Currents leads voltage by 90 degrees in pure capacitance

ELI = E(Voltage) leads L(Inductor) I(Current).

ICE = I(Current) leads C(Capacitor) V(Voltage).
