Quick Answer: How is heating effect of electric current?

When an electric current is passed through a conductor, the conductor becomes hot after some time and produces heat. The reason for this change in temperature is the transformation of some electric energy passing through the conductor into heat energy.

How is heating effect of electric current used in electric bulb?

Electric bulb works on the principle of heating effect of electric current. When electric current passes through a very thin, high resistance tungsten filament of an electric bulb, the filament becomes white hot and emits light.

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.

What are the important applications of an electric bulb?

What is the formula of heating effect?

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 heat effect?

Prolonged exposure to extreme heat can cause heat exhaustion, heat cramps, heat stroke, and death, as well as exacerbate preexisting chronic conditions, such as various respiratory, cerebral, and cardiovascular diseases.
