What is galvanic cell and working

The Galvanic Cells is a device that transforms chemical energy into electric energy. It is the common application of electro chemistry which is also called battery. It was invented by Luigi Galvani and Alessandro Volta which has capability of producing a voltage. It has two conductive electrodes, called the anode and the cathode. The anode is an electrode where oxidation occurs. The cathode is an electrode where reduction takes place.

In this cell there is a container in which a solution of concentrated Copper Sulphate (CuSO₄) is kept inside it and a copper rod is inserted inside the solution of CuSO₄ which act like cathode. Inside this container a porous container is kept in which concentrated Sulphuric Acid (H₂SO₄) is filled in which a zinc rod is inserted in it which acts like anode. Thus when a wire is connected through copper rod and zinc rod an electric current starts to flow.
