A heating element, as used on the rear window of a car, consists of three strips of aresistive material, joined, as shown in the diagram, by strips of copper of negligibleresistance. The voltage applied to the unit is 12 V and heat is generated at a rate of 40W.(a)i. Calculate the total resistance of the element.ii. Hence show that the resistance of a single strip is about 11 Ω.(b) If each strip is 2.6 mm wide and 1.1 mm thick, determine the length of each strip.resistivity of the resistive mate
