7. Related to resistance is a term called resistivity. Resistivity depends on material type, and is a number with units of Om. When multiplied by a wire's length divided by its area, resistivity yields the overall resistance of that length of wire: A R= resistivity (L/A) The wire heating element of an electric toaster is 190 cm long, and has a diameter of 0.05 cm. If the heating element is made of nichrome (which has a resistivity of 1.1x10 Om), what is the overall resistance of the wire?
