A variable, opposite external potential (Eext) is applied to the cell ZnZn2+(1M)∥Cu2+(1M)Cu of potential 1.1 V. When Eext 1.1V respectively, electrons flow from: - Sri Chaitanya Infinity Learn Best Online Courses for NCERT Solutions, CBSE, ICSE, JEE, NEET, Olympiad and Class 6 to 12

The cell will function as a galvanic cell if $E_{ext} < 1.1 V$ , at which point electrons will flow from the anode to the cathode.

$E_{ext} > 1.1 V,$ causes electrons to flow from cathode to anode, causing the cell to function as an electrolytic cell.

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