In Daniell cell (Zn | Zn²⁺ || Cu²⁺ | Cu), electron flow in external circuit:
ANo flow
BZn → Cu (anode to cathode externally)
CBoth directions
DCu → Zn
Answer & Solution
Correct answer: B. Zn → Cu (anode to cathode externally)
In Daniell cell, electrons flow from Zn (anode, oxidized) to Cu (cathode, reduced) through external circuit. Conventional current flows from Cu to Zn. EMF ≈ 1.1 V at standard conditions.
