A coil is to be used as an immersion heater for boiling water. The coil is to operate at \( 220 \mathrm{~V} \) and is to heat \( 500-\mathrm{g} \) of water from \( 20^{\circ} \mathrm{C} \) to \( 100^{\circ} \mathrm{C} \) in 6 minutes. The specific heat capacity of water is 4190 \( \mathrm{J} / \mathrm{kg} \mathrm{C}^{\circ} \). (a) What must be the resistance of the coil? (b) if the coil is to be made of Nichrome which will be formed into a wire of diameter \( 1.0 \mathrm{~mm} \), what must be the total length of the wire used to make the coil? Resistivity of Nichrome is \( 150 \times 10^{-8} \Omega \mathrm{m} \) Show the solution
