What is the direction of electron flow and current when Eext is less than 1.1 V in a Daniell cell?

Options

  1. AElectrons flow from Cu to Zn, and current flows from Zn to Cu.
  2. BElectrons flow from Zn to Cu, and current flows from Cu to Zn.
  3. CNo flow of electrons or current.
  4. DElectrons flow from Zn to Cu, and current flows from Cu to Zn.

Correct answer

B. Electrons flow from Zn to Cu, and current flows from Cu to Zn.

Step-by-step solution

When Eext is less than 1.1 V, electrons flow from Zn rod to Cu rod, and current flows from Cu to Zn.
