Disadvantages Of Heating Effect Of Electric Current

Heating effect of electric current.

Disadvantages of heating effect of electric current. A fuse is rated for a specific amperage. Following are the disadvantages of the heating effect of current. Fuse is a basic electrical part used to protect appliances. The heat produced damages the insulation of connecting wires.

1 when an electric current flows through the conductor a part of it is converted into heat energy. Disadvantages of the heating effect of current. An electric fuse also uses the 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.

Ohm s law and resistance. 3 reduces the life of several components in the. An electric fuse also uses the heating effect of electric current. Also in electric fuse heating of over rated current heats and melts the fuse wire to protect the electrical appliances.

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. 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.

Disadvantages of the heating effect of current. Electric current and circuit diagrams. As you may have guessed heating stuffs is the benefit of heating effect of electric current. Browse more topics under electricity.

Heating effect is used in electric iron electric oven and electric heater etc. This equation is the joule s equation of electrical heating. Various electrical components can get damaged. In electric bulb electric current is heating the tungsten filament to produce light.

Wastage of energy during power transmission in overhead cables is a. 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. Fires can be caused if inflammable objects are pres. Wastage of energy during power transmission in overhead cables is a.

A fuse is rated for a specific amperage. When the current through it exceeds its rating the heat produced melts the fuse wire thus opening the circuit. Electric potential and potential difference. In simple terms the advantage of heating effect of current is heaters like water heater room heaters etc.

The following are the disadvantages of heating effect of electrical current.
