An electric cell is a device, which converts chemical energy into electrical energy. It has two terminals, which are made up of metal: one terminal is positive, while the other one is negative. When the two terminals are connected to an electrical device, electric current flows through it.
- An electrochemical cell consists of electrodes namely cathode and anode.
- The non-spontaneous reaction is controlled by an external source of current.
- The decomposition of an electrolytic solution by passing current, which results in the liberation of corresponding gases or metals is known as electrolysis.
