An insulating pipe of $$cross-sectional$$ are a A contains an electrolyte which has two types of ions: their charges being −e and $$+2e$$.  A potential difference applied between the ends of the pipe result in the drifting of the two types of ions, having drift speed $$=$$ v $$(-ve$$ $$ion)$$ and $$v/4$$ $$(+ve$$ $$ion)$$.Both ions have the same number per unit volume $$=$$ n. The current flowing through the pipe is
