The heating element of a home toaster produces 1.2 kW (k=kilo, 103) of heat when operated at 220 V. c) What is the resistance of the heating element? Ω b) If the heating element is made from Nichrome wire with a rectangular cross-section of sides 0.4 mm and 1.5 mm, what must be the total length of the wire? The resistivity of Nichrome at the operating temperature is 1.3x10-6 2.m. c) What is the current (assumed to be DC) in the wire?
