**Question:**

A heating element has a resistance of $100 \Omega$ at room temperature. When it is connected to a supply of $220 \mathrm{~V}$, a steady current of 2 A passes in it and temperature is $500^{\circ} \mathrm{C}$ more than room temperature. What is the temperature coefficient of resistance of the heating element?
