### What is Faraday's law of Electrolysis? Faraday's law of electrolysis The relationship between the amount of electric charge passing through an electrolyte and the amount of substance deposited at the electrode was introduced by Faraday in 1834 as the laws of electrolysis. 1. first law The mass of the substance deposited or liberated at any electrode is directly proportional to the amount of charge passed" Let this proportionality be called w = zq.  can be made in equality by Where z is the proportionality constant called the electrochemical equivalent.  It is the mass of matter in grams that is deposited or released by passing a coulomb of charge. 2. Second Law The mass of a substance that is deposited or liberated at an electrode when a certain amount of charge is passed is directly proportional to its chemical equivalent mass". that is w a E where w is the mass of the substance in grams while E is its chemical equivalent weight per gram equivalent. This law can be explained as follows. Consider three reactio

### Definition of Faraday's Law of Induction Faraday's Law of Induction Faraday’s Law of Induction describes how an electrical current produces a field of force and, conversely, how a changing force field generates an electrical current during a conductor. In 1830, magnetic induction was invented by physicist Michael Faraday.  But Joseph Henry, an American physicist, made the same discovery about the same time, independently at the University of Texas. It is impossible to overstate the importance of Faraday’s discovery. Magnetic induction makes possible the electrical Motors , Generators  and Transformers  that form the muse of recent technology. By understanding and using induction, we've an electrical power system and lots of of the items we plug into it. Faraday's law was later found, more broadly, in Maxwell's equation. Maxwell's equation was developed by Scottish physicist James Clerk Maxwell to establish the relationship between electricity and magnetism.  It essentially united an electromagnet fo
