## Peltier Effect

In 1834, a French scientist Peltier discovered that if the junctions are at the same temperature and a current is passed through the circuit of the Thermocouple, heat is produced at one Junction and absorbed at the other i.e. one junction (former) is heated and the other junction (later) is cooled. This is known as Peltier … Read morePeltier Effect

## Thomson Effect | Positive & Negative Types

The absorption or evolution of heat energy, if a current is allowed to flow in a conductor having its different parts of different temperatures is known as Thomson effect. or When a current flows through an unequally heated conductor, there is an absorption or evolution of heat in the body of the conductor. This is … Read moreThomson Effect | Positive & Negative Types

## Maxwell’s Right Hand Grip Rule And Right Handed Cork Screw Rule

When the current flows to the conductor, a magnetic field is produced around it. The nature of magnetic field around a straight current carrying conductor is like concentric circles. The center of these concentric circle is axis of the current carrying conductor. The direction of these circular magnetic lines is dependent upon the direction of flow … Read moreMaxwell’s Right Hand Grip Rule And Right Handed Cork Screw Rule

## Fleming’s Left Hand Rule And Right Hand Rule

When a current carrying conductor is placed in the magnetic field, conductor experiences a force due to the magnetic field. While when a conductor moved in a magnetic field, an emf is induced across the conductor according to Faraday’s law of electromagnetic induction. J. A. Fleming introduced two important rules to determine the direction of … Read moreFleming’s Left Hand Rule And Right Hand Rule

## Faraday’s Law And Lenz’s Law Of Electromagnetic Induction

In 1831, Micheal Faraday formulated two important laws on the basis of certain experiments that shows a relationship between the electric circuit and magnetic field. These laws are called Faraday’s laws of electromagnetic induction. Faraday’s First Law According to Faraday’s First Law, Whenever a conductor is placed in a varying magnetic field, an EMF is … Read moreFaraday’s Law And Lenz’s Law Of Electromagnetic Induction

## Kirchhoff Current Law and Kirchhoff Voltage Law

There are some simple relations between currents and voltages of different branches of an electrical circuit. These relations are determined by some elementary laws that are known as Kirchhoff laws or more exactly Kirchhoff Current and Voltage laws. These laws are first derived by Gustave Robert Kirchhoff and therefore these laws are also called as Kirchhoff … Read moreKirchhoff Current Law and Kirchhoff Voltage Law
