3. A 500-W heating coil designed to operate from 110 V is made of Nichrome wire 0.500 mm in diameter. (a) Assuming that the resistivity of the Nichrome remains constant at its 20.0 °C value, find the length of wire used. (b) Now consider the variation of resistivity with temperature. What power will the coil actually deliver when it is heated to 1200 °C?
