## 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 more

## 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 more

## Electrical Resistance | Resistor materials

The property of a material that opposes the flow of current through it, is called electrical resistance or simply resistance. The symbol of resistance is shown in the fig. 1. Practically, the electrical components that offers certain opposition (resistance) to the flow of current in the circuit is known as resistor. Fig. 1(b) shows some … Read more

## What is Choke Coil – Applications

If someone chokes a person, they can’t breathe, the flow of air is stopped. The name Choke comes from the same idea. There is some energy that we want to Choke or prevent flowing in our circuit in or out of our circuit. We might want to prevent the power or ground lines in a … Read more

## Difference Between Ground and Neutral

Ground or earth in a main (AC power) electrical wiring system is a conductor that exists primarily to help protect against faults and which in normal operation does not carry current. Neutral is a circuit conductor that may carry current in normal operation, and which is usually connected to earth. In-house wiring, it is the … Read more

## Why don’t we use copper wire as a fuse wire?

Why don’t we use copper wire as a fuse wire Fuse is a Safety device which protects an electrical device from fault. Whenever there is a fault, a short circuit current will flow that leads to the generation of high heat. This heat will damage the electrical appliance if the circuit does not open in … Read more

## Permittivity of a Material

Permittivity of a Material The permittivity is the property of the material which shows the development of an electric field in the presence of an external electric field. In other words, It is the ability of the material to develop the electric field in the presence of an external electric field. It is represented by the … Read more
