1 when an electric current flows through the conductor a part of it is converted into heat energy. Fuse is a basic electrical part used to protect appliances. As we know that to maintain the electric current through a wire cells or battery expanse energy this energy is used by gadgets to do some works whereas rest is used to rise the temperature of gadgets which is directly proportional to the square of the current the resistance of wire and the time for which electric flows. A fuse is rated for a specific amperage.

An electric fuse also uses the heating effect of electric current. An electric fuse also uses the heating effect of electric current. As you may have guessed heating stuffs is the benefit of heating effect of electric current. 2 the heat produced can damage the insulation and other electrical components or even cause a fire.

Ohm s law and resistance. But in electrical system heating effect of current increases the resistance thus resulting in increase in voltage drop increased loss of. This is a video for grade 8 10 students that discusses about heating effects of electric current and related explanation. In simple terms the advantage of heating effect of current is heaters like water heater room heaters etc.

In electric bulb electric current is heating the tungsten filament to produce light. Hence the heating effect produced by an electric current i through a conductor of resistance r for a time t is given by h i 2 rt. Simply you re converting electrical energy to heat energy thanks to this effect of current. Also in electric fuse heating of over rated current heats and melts the fuse wire to protect the electrical appliances.

When the current through it exceeds its rating the heat produced melts the fuse wire thus opening the circuit. Disadvantages of the heating effect of current. Following are the disadvantages of the heating effect of current. Wastage of energy during power transmission in overhead cables is a.

A fuse is rated for a specific amperage. Heating effect is used in electric iron electric oven and electric heater etc. Electric potential and potential difference. Heating effect of electric current.

When the current through it exceeds its rating the heat produced melts the fuse wire thus opening the circuit. 3 reduces the life of several components in the. This is a waste of energy. The following are the disadvantages of heating effect of electrical current.

This equation is the joule s equation of electrical heating.
