Q. A variable, opposite external potential ($E_{ext}$) is applied to the cell
$Zn\left|\left(Zn\right)^{2 +} \left(\right. 1 \,M \left.\right) \left|\right. \left|\right. \left(Cu\right)^{2 +} \left(\right. 1 \,M \left.\right) \right|Cu$ , of potential $1.1\,V$ . When $E_{ext} < 1.1\,V$ and $E_{\text{ext }}>1.1\,V$ , respectively electrons flow from :

Solution:

Cell is behaving as galvanic when $E_{ext} < 1.1\,V$ and as electrolytic when $E_{ext}>1.1\,V$
