The heat produced damages the insulation of connecting wires.

Disadvantages of heating effect of electric current.

Following are the disadvantages of the heating effect of current. When the current through it exceeds its rating the heat produced melts the fuse wire thus opening the circuit. Heating effect of electric current. Fires can be caused if inflammable objects are pres.

Electric potential and potential difference. Wastage of energy during power transmission in overhead cables is a. Heating effect is used in electric iron electric oven and electric heater etc. Heating effect of electric current.

A fuse is rated for a specific amperage. The following are the disadvantages of heating effect of electrical current. In electric bulb electric current is heating the tungsten filament to produce light. 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.

An electric fuse also uses the heating effect of electric current. Disadvantages of the heating effect of current. A fuse is rated for a specific amperage. Wastage of energy during power transmission in overhead cables is a.

This is a video for grade 8 10 students that discusses about heating effects of electric current and related explanation. This equation is the joule s equation of electrical heating. But in electrical system heating effect of current increases the resistance thus resulting in increase in voltage drop increased loss of. When the current through it exceeds its rating the heat produced melts the fuse wire thus opening the circuit.

Also in electric fuse heating of over rated current heats and melts the fuse wire to protect the electrical appliances. 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. Fuse is a basic electrical part used to protect appliances. Simply you re converting electrical energy to heat energy thanks to this effect of current.

2 the heat produced can damage the insulation and other electrical components or even cause a fire. As you may have guessed heating stuffs is the benefit of heating effect of electric current. Browse more topics under electricity. In simple terms the advantage of heating effect of current is heaters like water heater room heaters etc.

This is a waste of energy. An electric fuse also uses the heating effect of electric current. Disadvantages of the heating effect of current. Ohm s law and resistance.

3 reduces the life of several components in the.
