Question

What is the difference between wires used for making electric circuit and electric bulb
filament and element of heater?​

Answer 1

Answer:

wire used for making electric circuit like copper has less resistance and electrons can easily flow through it.

while wire used in making filament of electric bulb like tungsten have high resistance. they stop the flow of electrons because of which heat and light is produced.

Answer 2

Circuit wire: Low resistance, lower melting point, thick in diameter

Electric bulb filament: high resistance, higher melting point, thin in diameter

Element of heater: Highest resistance, highest melting point

Explanation:

• Circuit wires have lesser resistance, lower melting point and higher conductivity whereas the wire of filament bulb has high resistance and lower work function which excites the electrons of the material with the generated heat of electric current which releases light energy.

• On the other hand the element of a heater is made of much higher resistance wire having a resistance highest among those discussed here. It also has the highest melting point and hence suitable to produce heat of electricity.

Heat of electricity as given by Joule's law:

$Q=I^2.R.t$

where:

I = current in the circuit

R = resistance

t = time for which the current flows

TOPICS: Joule's Law, resistance, work function,
