# Solution - Aheating 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. - Temperature Dependence of Resistance

ConceptTemperature Dependence of Resistance

#### Question

Aheating element using nichrome connected to a 230 V supply draws an initial current of 3.2 A which settles after a few seconds toa steady value of 2.8 A. 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 × 10−4 °C −1.
