A heating element using nichrome connected to a 230 V supply draws an initial current of 3.2 A which settles after a few seconds to a steady value of 2.8 A. What is the steady temperature of the heating element if the room temperature is `27^(@)C` ? Temperature coefficient of resistance of nichrome averaged over the temperature range involved is `1.70xx10^(-4) C^(-1)`.
