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 2.8A. What is the steady temperature of the heating element if the room temperature is 27.0^@C. Temperature coefficient of resistance of nichrome averaged over the temperature range involved is 1.70 xx 10^(-4) ""^@C^(-1)
