A galvanic cell is a type of electrochemical cell that has the ability to convert the chemical energy produced by the redox reaction into electrical energy. The galvanic cells are also known as the voltaic cells. In the redox reactions, there is a spontaneous movement of electrons between the participating species. Therefore, the reactions generate energy which is utilized in doing some work.
A galvanic cell is composed of two half cells that are connected with one another with the help of a salt bridge. The electrodes are dipped in the electrolyte present in both the half cells. The half cells are connected to a voltmeter and a switch. The cathode is made up of copper and the anode is made up of zinc in this type of cell.
