The effect of 'polarisation' is to
A) determine the direction of current supplied by the cell
B) reverse the direction of current supplied by the cell
C) significantly reduce the electromotive force produced by the cell

Question

Quizplus · Accepted Answer

Polarisation occurs when the byproducts of electrochemical reactions build up on the electrodes. This build-up creates a resistance that impedes the flow of current and reduces the cell's overall electromotive force. Therefore, it significantly reduces the electromotive force produced by the cell.
