Question

If nichrome has the heating effects of current then why is it not used in bulb as the filament?

Answer 1

Nichrome wire, an alloy of nickel and chromium, and often iron (or other elements) is good for making heaters but not lamps.

At rated voltages, nichrome will glow orange-red, not the bright white that is needed for illumination. If you increase the voltage to get a brighter color, the nichrome will burn open (melt.)
So it cannot be used in lambs.
