- ✓If $E _{ ext }>1.1\, V , Zn$ dissolves at $Zn$ electrode and $Cu$ deposits at $Cu$ electrode
- BIf $E _{\text {ext }}>1.1\, V , e ^{-}$ flows from $Cu$ to $Zn$
- CIf $E _{ ext }=1.1 \,V ,$ no flow of e $^{-}$ or current occurs
- DIf $E _{\text {ext }}<1.1\, V , Zn$ dissolves at anode and $Cu$ deposits at cathode
