Question

1) what are conductor different from insulator ?

2) why is tungsten metal used for making filaments of incandescent lamps
​

Answer 1

${\boxed{\boxed{Hallo}}}$

1)✨Conductor: Substance that allow the electricity to pass through them.

✨Insulator : Substance which resist electricity.

✨Conductor: Allows electric current to flow through it freely.

✨Insulator: It prevents any electric current flowing through it.

✨Example for conductor: COPPER

✨Example for Insulator: RUBBER

2) Tungsten has high melting point and resistivity.

It does not burn very easy at a high temperature.

The electric lamps glow at very high temperatures. Hence, tungsten is mainly used for making filaments of incandescent lamps.
