We use electricity to run different things like fans, doorbells, heaters, bulbs, and so on. These devices make use of different effects of electric current such as the magnetic effect and the heating effect. Another often-used effect of electric current is its chemical effect. When electricity is passed through certain liquids, chemical changes take place. Some of these changes are useful to us.
How do we pass electricity through a liquid? We put two electrodes in the liquid and apply a voltage across them. In a circuit, an electrode is a conductor that is in contact with a nonmetallic thing like a liquid or gas. The electrode connected to the positive terminal of a battery is called the anode, and the electrode connected to the negative terminal is called the cathode.
