A heating element using nichrome connected to a math xmlns=http://www.w3.org/1998/Math/MathMLmn230/mnmi mathvariant=normalV/mi/math supply draws an initial current of math xmlns=http://www.w3.org/1998/Math/MathMLmn3/mnmo./momn2/mnmo /momi mathvariant=normalA/mi/math which settles after a few seconds to steady a value of math xmlns=http://www.w3.org/1998/Math/MathMLmn2/mnmo./momn8/mnmo /momi mathvariant=normalA/mi/math. what is the steady temperature of the heating element if the room temperature is span class=math inline\(27^{\circ}\text{C }\)/span?temperature coefficient of resistance of nichrome averaged over the temperature range involved is span class=math inline\(1.70 \times 10^{- 4}C^{- 1}\)/span.
