Electric resistance is the opposite property of electrical conductivity in an electrical circuit.
If a material is having good electrical conductivity, current can freely flow through that material.
However, if the material is having low electrical conductivity, the current can not easily pass through such materials.
If you still pass the current through a material having a high resistance, then the current passed through such materials get converted to heat energy .
If the heat energy generated is so high , the material can melt away.
But tugsten filament which melts at 3400°C is used as the filament in electrical bulbs .
Because of the high resistance of the tungsten metal , the entire current passed in the tungsten filament is converted to heat.
Because of this heat , tungsten filament becomes red hot emitting light .
However , because of the high melting point of tungsten , the filament can not melt , but as it becomes red hot , it emits light.
This is how the elextric bulbs glow & give us light.
