NCERT Exercise 3.6 - Current Electricity
Question: 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? Temperature coefficient of resistance of nichrome averaged over the temperature range involved is 1.70 × 10⁻³ °C⁻¹.
Answer: Steady temperature of the heating element = **867.5 °C**.
