In the context of alternating current theory, the imaginary unit is customarily given the symbol jj rather than ii , so that the symbol ii is available, if need be, for electric currents.

This is so regardless of the form of the variation of V: it could be sinusoidal, it could be constant, or it could be something quite different.
