Disadvantages Of Heating Effect Of Electric Current Class 10

The heat produced can damage the insulation on wire damage electrical components or cause fires.

Disadvantages of heating effect of electric current class 10.

Electric current and circuit diagrams. This is a waste of energy. To prevent this electric fuse is kept in series with the device. Browse more topics under electricity.

The heating of resistor because of dissipation of electrical energy is commonly known as heating effect of electric current. Class 10 science home page. Following are the disadvantages of the heating effect of current. Electric fuse is a piece of wire made from an alloy of low melting point but good conductivity such as alloy.

Fires can be caused if inflammable objects are present nearby. Please name and if possible explain the disadvantages. In most of the cases the heating effect is the wastage of energy. When electric current is supplied to a purely resistive conductor the energy of electric current is dissipated entirely in the form of heat and as a result resistor gets heated.

Heating effect of electric current cannot be prevented. 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. What are the disadvantages of heating effect of electric current.

The law implies that the heat produced in a resistor is directly proportional to the square of current for a given resistance it means if we double the current the heat becomes 4 times if we half the current the heat becomes 1 4 times hence more the current. The heat produced damages the insulation of connecting wires. What is formula for heating effect of electric current h i 2 rt how is heat formula derived this is known as joule s law of heating. Devices like tvs music system and computers have vents to allow air to cool them.

The person who gives the most ages will be chosen as the best answer. When electric energy is. Computers even have fans f. Flowing electric current can cause heat.

An efficient circuit will. This equation is the joule s equation of electrical heating. 2 the heat produced can damage the insulation and other electrical components or even cause a fire. Please give as many as possible like short curciut and all.

Various electrical components can get damaged. In many cases the heating effect of electric current reduces the lifespan of an appliance because it damages the. The following are the disadvantages of heating effect of electrical current. Heating effect of electric current.

Some examples are as follows. Practical applications of the heating effect of electric current. A very important application of heating effect of electric current is electric fuse. 1 when an electric current flows through the conductor a part of it is converted into heat energy.

Under short circuit condition excess current flows through the circuit. Class 10 heating effect of electric current. Higher the current the amount of heat generation is also large.
