Use of a Non-Polarizable Counter Electrode

If we combine the working electrode with a highly non-polarizable counter electrode, the change of potential, 6 A )) at the counter electrode will be negligible compared to that at the working electrode, 5( A (t)), and practically all the change in potential observed will occur at the working electrode.
