What are the two families of circles and arcs that make up a Smith chart?
- A.Inductance and capacitance
- B.Reactance and voltage
- C.Resistance and reactance (correct answer)
- D.Voltage and impedance
WhyThe two families of circles and arcs that make up a Smith chart represent resistance and reactance. A Smith chart is made up of two overlapping families of curves: circles of constant resistance and arcs of constant reactance, together forming the grid that lets any complex impedance be located as a single point, answer C. Inductance and capacitance, reactance and voltage, and voltage and impedance don't correctly describe the chart's actual resistance-and-reactance curve families.
