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