Heya soyamm! We know that P =V^2/R So, R =V^2/P = 220 X 220 /1000 =48.4 ohm Thus resistance of the heating filament is 48.4 ohm Hope that helps!

Hello friend here is your answer.
Since P(power)= Vsquare/R.
Here we have V=220volt and P= 1000watt.
=>1000=220×220/R
=>R=220×220/1000
=>R=48.4ohm
Thus resistance of heating filament will be 48.4 ohm
