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.

Fires can be caused if inflammable objects are pres. When the current through it exceeds its rating the heat produced melts the fuse wire thus opening the circuit. 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. 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. An electric fuse also uses the heating effect of electric current.
