Question

Why residual current flowing through electrolytic cell?

Answer 1

Hello everyone...

Voltaic cells are driven by a spontaneouschemical reaction that produces an electric current through an outside circuit. These cells are important because they are the basis for the batteries that fuel modern society. But they are not the only kind of electrochemical cell. The reverse reaction in each case is non-spontaneous and requires electrical energy to occur.

Hope this helps you...
