Fleming’s right-hand rule is a mnemonic device used in electromagnetism to determine the direction of the force acting on a current-carrying conductor placed in a magnetic field. It is named after the British physicist John Ambrose Fleming. The rule states that if you stretch out your right hand and orient it in a specific way, …
Faraday’s laws of electrolysis describe the quantitative relationship between the amount of substance produced or consumed during electrolysis and the amount of electric charge passed through an electrolyte. These laws were formulated by the English scientist Michael Faraday in the 1830s and are fundamental principles in electrochemistry. Faraday’s First Law: The amount of a substance …
