GALVANIC CELL Meaning and
Definition
-
A galvanic cell, also known as a voltaic cell or an electrochemical cell, refers to an electrochemical device that converts chemical energy into electrical energy through a redox reaction. It consists of two electrodes, an anode and a cathode, which are immersed in an electrolyte solution. The anode is the electrode where oxidation occurs, while the cathode is the electrode where reduction takes place. The electrolyte is a medium that allows the movement of ions between the electrodes.
The galvanic cell operates based on the principles of redox reactions, where one electrode loses electrons (oxidation) and another electrode gains electrons (reduction), resulting in the production of a flow of electrons from the anode to the cathode, generating an electric current. This flow of electrons can be harnessed to power various electronic devices.
The key components of a galvanic cell include the electrodes, electrolyte, and a salt bridge or porous membrane that allows the ions to move between the two half-cells to maintain charge balance. The voltage generated by the cell is determined by the difference in the potential of the two electrodes, also known as the cell potential or electromotive force (EMF). Galvanic cells find numerous applications in batteries, fuel cells, and other devices that require portable and reliable sources of electrical energy.
Overall, a galvanic cell is a device that utilizes the chemical reactions occurring at the electrodes to convert chemical energy into electrical energy, making it a vital technology across various fields.

Etymology of GALVANIC CELL
The word "galvanic" in "galvanic cell" is derived from the name of the Italian physician and physicist Luigi Galvani (1737-1798). Galvani is known for his work on bioelectricity, specifically for his discovery of animal electricity. He conducted experiments with dissected frog legs, which led to the understanding that electrical currents are generated by the animal body.
The term "galvanic cell" was coined in honor of Luigi Galvani's contributions to the study of electrical phenomena. It refers to an electrochemical cell that converts chemical energy into electrical energy through redox reactions.
