A heating element using nichrome connected to a 230V supply draws an initial current of 3.2A which settles after a few seconds to a steady value of 2.8A. What is the steady temperature of the heating -element, if the room temperature is `27.0^(@)`C? Temperature cofficient of resistance of nichrome averaged over the temperature range involved is `1.70xx 10^(-4@)C^(-1).`
