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.
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 27.0 °C? The Temperature coefficient of resistance of nichrome averaged over the temperature range involved is 1.70 × 10–4 °C–1.
