Cell We have seen that when a current passes through the solution of an electrolyte, chemical changes take place i.e., electrical energy is converted into chemical energy. The converse of this is also true i.e., we can convert chemical energy into electrical energy. The device which accomplishes this job is called a cell. A cell is a source of e.m.f. in which chemical energy is converted into electrical energy. A cell essentially consists of two metal plates of different materials immersed in a suitable solution. The plates are called electrodes and the solution is called electrolyte. The magnitude of e.m.f. of a cell depends upon (i) the nature of material of electrodes used and (ii) the nature of electrolyte | |
