A) anode to cathode through the solution
B) cathode to anode through the solution
C) anode to cathode through the external circuit
D) cathode to anode through the external circuit
Correct Answer: C
Solution :
In a galvanic cell, oxidation (i.e. removal of \[{{e}^{-}}\]) occurs at anode. These electrons flow through external circuit from anode to cathode. Therefore the direction of current in external circuit is from cathode \[(-\upsilon e)\] to anode \[(+\upsilon e)\].
