 # Quick Answer: What Are The Applications Of Heating Effect Of Current?

## What are the applications of heating effect of electric current?

The heating effect of electric current is used in the following applications: Electric Bulb: In an electric bulb, the filament of bulb gives light because of heating effect of electricity.

The filament of bulb is generally made of tungsten metal; having melting point equal to 3380°C..

## What is Joule’s heating effect of current?

Joule heating is the physical effect by which the pass of current through an electrical conductor produces thermal energy. This thermal energy is then evidenced through a rise in the conductor material temperature, thus the term “heating”.

## What is the formula of heating effect of current?

Hence the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t is given by H = I2Rt. This equation is called the Joule’s equation of electrical heating.

## What is heating effect of current Class 7?

When electric current flows through a conducting wire, the temperature of wire increases. This is called heating effect of electric current. Devices Which Work on Heating Effect of Electric Current: Incandescent bulb is an example of a device which works because of the heating effect of electric current.

## What is heating effect of electric current class 10th?

When electric current is supplied to a purely resistive conductor, the energy of electric current is dissipated entirely in the form of heat and as a result, resistor gets heated. The heating of resistor because of dissipation of electrical energy is commonly known as Heating Effect of Electric Current.

## Is electric fuse and application of heating effect of current?

Applications of Heating Effect of Current The Electric Fuse: Copper or zinc can be used as the fuse element. When there is an excess of current flow through the electrical circuit, the heat generated increases as well and melts the fuse, thereby breaking the circuit.

## What are the four effects of electricity?

The ‘effects of electricity’ linemagnetic effect.heating effect.chemical effect.electric shocks.

## What is heating effect of current give two applications of heating effect on current?

Solution. When an electric current is passed through a high resistance wire, like nichrome wire, the resistance wire becomes very hot and produces heat. … The heating effect of current is used in electric irons, electric heaters, electric ovens, filament bulbs etc. and it is also utilised in electric fuses.

## What do you mean by the term heating effect of current?

(a) Heating effect of electric current : When an electric current is passed through a high resistance wire like nichrome, the resistance wire becomes very hot and produces heat. This is called heating effect of electric current.

## What is the formula of heat?

The heat capacity and the specific heat are related by C=cm or c=C/m. The mass m, specific heat c, change in temperature ΔT, and heat added (or subtracted) Q are related by the equation: Q=mcΔT.

## What is the importance of heat?

In physical science, heat is important to all aspects of life, especially plants and mammals. Plant life relies on heat, among other things, to survive as well. Heat is a result of energy, which can be beneficial as well as dangerous.

## What is Joules law of heating Class 10?

Joule’s law of heating states that when a current ‘i ‘ passes through a conductor of resistance ‘r’ for time ‘t’ then the heat developed in the conductor is equal to the product of the square of the current, the resistance and time. H = i 2 rt.

## What are the advantages of electric current?

Electricity can be used to heat either storage or continuous flow water heaters, and can also be used as a booster to solar or heat pump water heating systems. The advantage of electricity is its reliable supply.

## What are the disadvantages of heating effect of current?

Following are the disadvantages of the heating effect of current: 1) When an electric current flows through the conductor, a part of it is converted into heat energy. This is a waste of energy. 4) An additional cooling system needs to be added to the circuit to counter the heating effect.
