 # Question: What Is Joule Heating Effect Of Current?

## What does the Joule effect mean?

: production of heat by mechanical work, an electric current, or change in length due to magnetization — compare magnetostriction..

## What is heating effect of current class 10?

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 do you mean by the term heating effect of current?

When an electric current passes through a conductor (like a high resistance wire) the conductor becomes hot after some time and produces heat. This is called heating effect of Electric Current. Example 1. A bulb becomes hot after its use for some time.This is because of heating effect of electric current.

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

Advantages of heating effect of current 1)The heating effect of current is used in heating appliances such as electric iron, room heaters and water heaters. 2) An electric fuse is an important application of the heating effect of current. The working principle of the fuse is based on the heating effect of current.

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

1)The heating effect of electric current is utilised in the working of electrical heating appliances such as electric room heater , electric iron , immersion rod etc . many things. 2)The heating effect of electric of electric current is utilised electric bulbs (or electric lamp) for producing light.

## What is Joule’s heating effect class 10?

When an electric current is passed through a high resistance wire, like nichrome wire, the resistance wire becomes very hot and produces heat. This effect is known as heating effect of current or Joule’s law of heating.

## 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. b)The resistance of the filament used in the bulb. A 2.5 kW immersion heater is used to heat water.

## What is the formula of heat?

The equation for calculating heat energy is q=mCpΔT, where q is the heat variable, m is the mass of the object, Cp is the specific heat constant and ΔT is the temperature change.

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

The following are the disadvantages of heating effect of electrical current : The heat produced damages the insulation of connecting wires. Various electrical components can get damaged. Fires can be caused if inflammable objects are present nearby.
