Disadvantages Of Heating Effect Of Electric Current

When the current through it exceeds its rating the heat produced melts the fuse wire thus opening the circuit.

Disadvantages of heating effect of electric current.

Wastage of energy during power transmission in overhead cables is a. Disadvantages of the heating effect of current. The heat produced damages the insulation of connecting wires. Browse more topics under electricity.

Wastage of energy during power transmission in overhead cables is a. 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. 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. A fuse is rated for a specific amperage. Simply you re converting electrical energy to heat energy thanks to this effect of current. Also in electric fuse heating of over rated current heats and melts the fuse wire to protect the electrical appliances.

This equation is the joule s equation of electrical heating. Various electrical components can get damaged. Heating effect is used in electric iron electric oven and electric heater etc. The following are the disadvantages of heating effect of electrical current.

Fires can be caused if inflammable objects are pres. This is a waste of energy. Electric potential and potential difference. 2 the heat produced can damage the insulation and other electrical components or even cause a fire.

Ohm s law and resistance. Disadvantages of the heating effect of current. Fuse is a basic electrical part used to protect appliances. When the current through it exceeds its rating the heat produced melts the fuse wire thus opening the circuit.

In simple terms the advantage of heating effect of current is heaters like water heater room heaters etc. 3 reduces the life of several components in the. Electric current and circuit diagrams. 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.
