construction and working of electric cell


An electric cell is a device that converts chemical energy to electrical energy. A simple electric cell is made up of an electrolyte and two electrodes. The electrolyte is a conductive solution containing anions (negatively charged ions) which moves towards the anode (negative electrode)and cations (positively charged ions) moves towards the cathode (positive electrode). So, we have an excess of electrons in the anode (which is the negative terminal of the cell) and a deficiency of electrons in the cathode (which is the positive terminal of the cell).
