Disadvantages Of Heating Effect Of Electric Current

Various electrical components can get damaged.

Disadvantages of heating effect of electric current.

3 reduces the life of several components in the. Browse more topics under electricity. An electric fuse also uses the heating effect of electric current. An electric fuse also uses the heating effect of electric current.

1 when an electric current flows through the conductor a part of it is converted into heat energy. When the current through it exceeds its rating the heat produced melts the fuse wire thus opening the circuit. The following are the disadvantages of heating effect of electrical current. This is a waste of energy.

This is a video for grade 8 10 students that discusses about heating effects of electric current and related explanation. Wastage of energy during power transmission in overhead cables is a. As you may have guessed heating stuffs is the benefit of heating effect of electric current. Simply you re converting electrical energy to heat energy thanks to this effect of current.

Electric current and circuit diagrams. Fires can be caused if inflammable objects are pres. Following are the disadvantages of the heating effect of 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.

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

Heating effect of electric current. In electric bulb electric current is heating the tungsten filament to produce light. Heating effect is used in electric iron electric oven and electric heater etc. A fuse is rated for a specific amperage.

Heating effect of electric current. Electric potential and potential difference. In simple terms the advantage of heating effect of current is heaters like water heater room heaters etc. Ohm s law and resistance.

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

This equation is the joule s equation of electrical heating.
