APPLICATION OF HEATING EFFECT OF ELECTRIC CURRENT
by

1 Answer

Answer :

APPLICATION OF HEATING EFFECT OF ELECTRIC CURRENT:
 In an electric circuit, the unavoidable heating can
increase the temperature of the components and alter
their properties.
 Heating effect has many application like iron, toaster,
oven, kettle, heater etc.
 An electric bulb consists of a filament. Filament becomes
hot and emits light. Te bulbs are filled with chemically
inactive nitrogen and argon gases to prolong the life of
filament.
 An electric iron consists of a coil of high resistance by
mica sheets. Mica sheet is bad conductor of electricity
and good conductor of heat. Coil is placed in the block
which is preventing from shock to the living.
 Fuse is used in electric circuit to prevent from excess
flow of current. Fuse element melts when excess current
is flowing through the circuit.
 In industry, soldering, welding, cutting, drilling and
working of electric furnaces.
 In surgery a fine heated platinum wire is used for cutting
tissues much more efficiently than a knife.
