Explanation:
Electrons flow from the electrode where oxidation occurs to the electrode where reduction occurs. In this cell, tin is oxidized at the left-hand Pt electrode (Sn2+ → Sn4+ + 2e−), releasing electrons into the external circuit. Those electrons are absorbed at the right-hand Ag electrode, where Ag+ is reduced to Ag. So the external circuit carries electrons from the tin side (anode) to the silver side (cathode).
