According to  Faraday’s Law, the relative motion between the magnetic field and conductor, the flux linkage changes and this change in flux induces a voltage across the coil.

Permanent Magnetic speakers commonly used in TV’s and Radios are perfect examples of Electromagnetic devices. Let’s see the operation of these devices which are based on the principle of electromagnetism. See the picture below. In order to convert electrical waves into audible sound, the speakers are designed. A metal coil is attached to a permanent…

1. Explain the function of a galvanic cell. Answer: A galvanic cell is an electrochemical cell used to supply electrical current by making the transfer of electrons through a redox reaction. During redox reactions, the galvanic cell converts chemical energy into electrical energy by transferring energy between the electrons. 2. How does an electrolytic cell…

The relationship between the quantity of electric charge passed through an electrolyte, and the amount of substance deposited at the electrodes was given by Faraday in 1834, in the form of the law of electrolysis. Faraday’s First Law When an electric current is passed through an electrolyte, the amount of substance deposited is proportional to…

Electrochemical cells are of two types: galvanic cells and electrolytic cells Galvanic Cell The galvanic cell converts chemical energy into electrical energy, i.e., electricity can be obtained with the help of a redox reaction. The oxidation and reduction take place in two separate compartments. Each compartment consists of an electrolyte solution and a metallic conductor,…

A spontaneous chemical process is one which can take place on its own, and in such a process, the Gibbs free energy of a system decreases. In electrochemistry, spontaneous reaction (redox reaction) results in the conversion of chemical energy into electrical energy. The reverse process is also possible where a non-spontaneous chemical reaction occurs by supplying electricity.…

Electrochemistry is the subdiscipline of Chemistry that deals with the study of the relationship between electrical energy and chemical changes. Chemical reactions that involve the input or generation of electric currents are called electrochemical reactions. Such reactions are broadly classified into two categories: Download Complete Chapter Notes of Electrochemistry Electricity can be produced when electrons move…
