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.

Disadvantages of 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. The heat produced damages the insulation of connecting wires. Heating effect is used in electric iron electric oven and electric heater etc. The following are the disadvantages of heating effect of electrical current.

2 the heat produced can damage the insulation and other electrical components or even cause a fire. Electric current and circuit diagrams. 1 when an electric current flows through the conductor a part of it is converted into heat energy. This is a waste of energy.

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. When the current through it exceeds its rating the heat produced melts the fuse wire thus opening the circuit. Following are the disadvantages of the heating effect of current. This equation is the joule s equation of electrical heating.

Disadvantages of the heating effect of current. In electric bulb electric current is heating the tungsten filament to produce light. A fuse is rated for a specific amperage. Wastage of energy during power transmission in overhead cables is a.

A fuse is rated for a specific amperage. Electric potential and potential difference. In simple terms the advantage of heating effect of current is heaters like water heater room heaters etc. Fuse is a basic electrical part used to protect appliances.

But in electrical system heating effect of current increases the resistance thus resulting in increase in voltage drop increased loss of. Also in electric fuse heating of over rated current heats and melts the fuse wire to protect the electrical appliances. Various electrical components can get damaged. Ohm s law and resistance.

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

Heating effect of electric current. Disadvantages of the heating effect of current. 3 reduces the life of several components in the. An electric fuse also uses the heating effect of electric current.

Fires can be caused if inflammable objects are pres.
