Question

What is an electric cell?

Answer 1

1. Definition: An electric cell is a device, which converts chemical energy into electrical energy.
2. 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.
3. An electrochemical cell consists of electrodes namely cathode and anode.
4. The non-spontaneous reaction is controlled by an external source of current.
5. The decomposition of an electrolytic solution by passing current, which results in the liberation of corresponding gases is known as electrolysis.

Therefore, an electric cell is a device used to generate electricity, or to make chemical reactions by applying electricity.
