Question

In electric bulb tungsten filament should have high melting point and high resistance give reason

Answer 1

Answer:

High melting point so that it doesn't melt when electricity passes through it.

high resistance so it gets heated enough to give out light

Answer 2

Answer:

because it is the resistance of the filament that causes the light bulb to glow.When the resistance is high, the filement becomes very hot and therefore a tungstan filement needs hight melting point and high resistance
