(N/A) In a Daniell cell,the standard cell potential is $1.1 \ V$.
When an external potential $E_{ext} < 1.1 \ V$ is applied,the cell continues to function as a galvanic cell.
$(1)$ The $Zn$ electrode acts as the anode (negative terminal) and the $Cu$ electrode acts as the cathode (positive terminal).
$(2)$ Electrons flow from the $Zn$ anode to the $Cu$ cathode through the external circuit,while the conventional current flows from the $Cu$ cathode to the $Zn$ anode.
