Disadvantages Of Heating Effect Of Electric Current

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.

Disadvantages of heating effect of electric current.

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. Heating effect of electric current. 1 when an electric current flows through the conductor a part of it is converted into heat energy.

This is a waste of energy. Wastage of energy during power transmission in overhead cables is a. Various electrical components can get damaged. Electric current and circuit diagrams.

In simple terms the advantage of heating effect of current is heaters like water heater room heaters etc. Disadvantages of the heating effect of current. As you may have guessed heating stuffs is the benefit of heating effect of electric current. An electric fuse also uses the heating effect of electric current.

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. 3 reduces the life of several components in the. The following are the disadvantages of heating effect of electrical current. Electric potential and potential difference.

Following are 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. Simply you re converting electrical energy to heat energy thanks to this effect of current. In electric bulb electric current is heating the tungsten filament to produce light.

When the current through it exceeds its rating the heat produced melts the fuse wire thus opening the circuit. Ohm s law and resistance. Browse more topics under electricity. Heating effect of electric current.

But in electrical system heating effect of current increases the resistance thus resulting in increase in voltage drop increased loss of. Disadvantages of the heating effect of current. The heat produced damages the insulation of connecting wires. When the current through it exceeds its rating the heat produced melts the fuse wire thus opening the circuit.

Fuse is a basic electrical part used to protect appliances. Wastage of energy during power transmission in overhead cables is a. Heating effect is used in electric iron electric oven and electric heater etc. A fuse is rated for a specific amperage.

Also in electric fuse heating of over rated current heats and melts the fuse wire to protect the electrical appliances.
