An isulating pipe of cross-section area A contains an electrolyte which has two types of ions: their charges being-e and + 2e . A potential difference applied between eht 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

Why the drift of the positive ions is not considered?

During the electrolysis, all the +ve ions move in
