Why does a Potentiostat have three
electrodes?
We would like to study the electrochemical events
taking place at one specific electrode…the
Working Electrode. The use of a three-electrode
potentiostat with a separate Reference and
Counter Electrode allows the potential at the WE
and the current at the WE to be measured with
little or no “interference” or “contribution” from
the other electrodes.
