Voltaic Cell

The discovery of the voltaic cell is credited to Alessandro Volta, an Italian physicist, in the late 18th century. In 1800, Volta developed the first practical electric battery, the voltaic pile. It consisted of alternating layers of zinc and silver disks separated by a salt bridge. This invention laid the foundation for modern batteries and electrical devices.

Zinc Disks

In a voltaic cell, the zinc disks serve as the anode, where a chemical reaction releases electrons. These electrons flow through a wire to the cathode, producing electrical energy. The zinc disk's role is to supply electrons and complete the circuit, enabling the cell to generate electricity.

Silver Disks

The silver disks in a voltaic cell serve as the cathode, where electrons from the anode (zinc) are received. This electron transfer at the copper cathode helps create an electric current, which is essential for the cell's function. In summary, the silver disk accepts electrons, allowing the cell to produce electricity.

Salt Bridge

A salt bridge in a voltaic cell consists of a paper or cloth soaked in an electrolyte solution. The electrolyte is often a salt, like potassium chloride (KCl), which provides ions (K+ and Cl-). This composition allows ions to move between the zinc and silver disks, ensuring a continuous flow of electrons and maintaining the cell's function.
