Photo voltaic cell converts light energy into electrical energy. It acts as a cell. It consists of a metal layer of copper over which a semiconductor layer of cuprous oxide coated with a thing film of silver or gol..

In order to study the working of an electrolytic cell and the phenomena of electrolysis it is important to know the working of a galvanic or a voltaic cell that generates electrical energy from its chemical reaction. In a simple voltaic cell a zinc ..

Electrodes: Copper (+ve) and Zinc (- ve) Electrolyte: dil. H 2 SO 4 (dilute sulphuric ac..

The fact that chemical reactions produce electrical effects was discovered accidentally in 1791 by Luigi Galwani, professor of anatomy at the University of Bologna, Italy. He found that an electric current flowed across two dissimilar metals between which was a moist substance. In his case, the moi..

The process of electrolysis is exactly opposite to one that takes place in a voltaic cell. A voltaic cell or a battery uses its chemical energy to produce electrical energy. While in electrolysis, electrical energy is used to bring about a chemical change. Hu..

Iron, which has to be continuously remain in contact with water, as in the body of ships, can be given a kind of electronic protection. Pieces of a more reactive metal, such as magnesium are attached to that part of the ship that remains under water. When in contact with water, the magnesium under..
