Cyclic voltammetry is the technique used to measure the electric current in an electrochemical cell.
The electrochemical cell is a device that uses a chemical reaction for generating electrical energy.
The cell which uses chemical reaction to generate the electric current through electrolysis is Galvanic cell.
In an electrochemical cell if the predicted voltage by the Nernst equation exceeds its limit and produces the current is measured through cyclic voltammetry.
In the electrochemical cell the working electrode helps in cycling the potential and due to this, the resulting current is measured.
The graph is drawn in between the working potential and the applied voltage.
