The heating effect of current is due to the resistance that occurs due to passage of electric current through a weak conductor.
The effect is used in light bulbs to light up the tungsten filament by heating it to a high temperature by electric current.
Tungsten is used as a filament as it has a high melting point, so it glows due to heat instead of melting away.
