Galvanic cell

Galvanic cell is a type of electrochemical cell that converts chemical energy into electrical energy. It is named after the Italian scientist Luigi Galvani, who first discovered the principles behind its operation.

Overview

A galvanic cell consists of two half-cells. Each half-cell consists of an electrode and an electrolyte. The two half-cells may use different chemical solutions. The reactions in the two half-cells are called redox reactions.

Operation

The operation of a galvanic cell is based on the transfer of electrons from one half-cell to the other. This transfer takes place through a wire that connects the two electrodes. The flow of electrons constitutes an electric current that can be used to do work.

Applications

Galvanic cells have many applications. They are used in batteries, fuel cells, and other devices that require the conversion of chemical energy into electrical energy.
