A heating element using nichrome connected to a 115 V supply draws a current of 1.6A which settles after a few seconds to a steady  value of 1.4 A. What is the steady  temperature of the heating element it the room temperature is `30^@C` ? Temperature coefficient of resistance of nichrome averaged over the temperature range involved is `1.7xx10^(-4).^(@)C^(-1)`.
