Question

The motor inside a blender can be modeled as a resistance in series with on Inductance, as shown in the given figure. The wall socket source is modeled as an ideal 120 Vrms voltage source in series with a 2-ohm output resistance. Assume the source frequency is w = 377 rad/s. Glven: R-10.5 ohm 202 w A w 120 V 20 mH Wall socket Blender motor References eBook & Resources Section Break Problem 07.021 7.
