Current in electrochemical cell
WebKey Points. • An electrochemical cell, also called galvanic or voltaic cell, is a device that produces an electric current from energy released by a spontaneous redox reaction in two half-cells. • The anode will undergo oxidation (loss of electrons) and reduction (gain of election) will happen at cathode. • Electrons leave the metal of ... WebThe processes responsible for the current flow in an electrochemical cell depend on which part of the cell you are in. For the metallic components (zinc, copper, copper connecting wire), electrons are responsible for the …
