Step 1 of 3

Galvanic cell

An electrochemical cell in which chemical energy formed during a spontaneous reaction is converted to electrical energy is called a galvanic cell. A galvanic cell is therefore used to produce electricity.

The reaction in a galvanic cell is a redox reaction in which electrons are transferred from the reducing agent to the oxidizing agent.

A galvanic cell consists of two half cell that is physically separated. The half cell at which oxidation occurs is the anode, and the reduction half cell is the cathode.

The electrons flow through an external circuit, causing current. A salt bridge is used to transfer ions between the half cells. A galvanic cell is also called a voltaic cell.

The voltage or cell potential of a galvanic cell is calculated as:
