A galvanic cell, or voltaic cell, named after Luigi Galvani, or Alessandro Volta respectively, is an electrochemical cell that derives electrical energy from spontaneous redox reactions taking place within the cell
Daniell cell consists of two half-cells. One half-cell is zinc rod dipped in 1M solutions. The other half-cell is copper rod dipped in a solution of 1M solutions. A porous partition or a salt bridge separates the two half-cells from each other. The two electrodes are connected together externally by a metal wire through a voltmeter are produced here so anode is the negative electrode. The copper rod acts as cathode where reduction takes place. Electrons are here so cathode is the positive electrode.
