A galvanic cell, which is also commonly referred to as a voltaic cell, is an electrochemical device that cleverly and efficiently converts chemical energy released during a spontaneous redox reaction directly into electrical energy. In this specialized device, oxidation and reduction half-reactions physically take place in separate compartments known as half-cells, allowing the spontaneous flow of electrons through an external metallic wire, thereby generating a useful electric current that can power external electrical devices and appliances effectively.
