Resistivity in AC Machines Formulas
Resistivity plays a crucial role in the design of electrical machines. It is a property that characterizes the resistance of a material to the flow of electric current. And is denoted by ρ. Resistivity is usually measured using the Ohm Meter for Electric Resistivity. Note that the value of Resistivity is always negative.
