An electric fuse also uses the heating effect of electric current.

Disadvantages of heating effect of electric current.

1 when an electric current flows through the conductor a part of it is converted into heat energy. An electric fuse also uses the heating effect of electric current. Fuse is a basic electrical part used to protect appliances. Wastage of energy during power transmission in overhead cables is a.

3 reduces the life of several components in the. Disadvantages of the heating effect of current. 2 the heat produced can damage the insulation and other electrical components or even cause a fire. Ohm s law and resistance.

Also in electric fuse heating of over rated current heats and melts the fuse wire to protect the electrical appliances. But in electrical system heating effect of current increases the resistance thus resulting in increase in voltage drop increased loss of. In electric bulb electric current is heating the tungsten filament to produce light. Electric current and circuit diagrams.

As you may have guessed heating stuffs is the benefit of heating effect of electric current. This equation is the joule s equation of electrical heating. Heating effect of electric current. Following are the disadvantages of the heating effect of current.

A fuse is rated for a specific amperage. Browse more topics under electricity. Fires can be caused if inflammable objects are pres. The heat produced damages the insulation of connecting wires.

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. Various electrical components can get damaged. Electric potential and potential difference. The following are the disadvantages of heating effect of electrical current.

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

Simply you re converting electrical energy to heat energy thanks to this effect of current. This is a video for grade 8 10 students that discusses about heating effects of electric current and related explanation. A fuse is rated for a specific amperage. Heating effect of electric current.
