In the Daniell cell,$Zn|Zn^{2+} || Cu^{2+}|Cu$,when an external voltage is applied such that $E_{\text{external}} > E_{\text{cell}}$,current flows from.........

Depict the galvanic cell in which the reaction $Zn_{(s)} + 2Ag^{+}_{(aq)} \rightarrow Zn^{2+}_{(aq)} + 2Ag_{(s)}$ takes place,further show:
$(i)$ which of the electrode is negatively charged,
$(ii)$ the carriers of the current in the cell,and
$(iii)$ individual reaction at each electrode.

At $25^{\circ} C$,the molar conductance at infinite dilution for the strong electrolytes $NaOH$,$NaCl$ and $BaCl_{2}$ are $248 \times 10^{-4}$,$126 \times 10^{-4}$ and $280 \times 10^{-4} \ S \ m^{2} \ mol^{-1}$ respectively. $\lambda_{m}^{o} Ba(OH)_{2}$ in $S \ m^{2} \ mol^{-1}$ is
