Question
What do the arcs on a Smith chart represent?
Answer Options
- A) Frequency
- B) SWR
- C) Points with constant resistance
- D) Points with constant reactance
Correct Answer: D
Explanation
The Smith Chart maps two properties of complex impedance: resistance (R) and reactance (X). The lines of constant resistance are drawn as circles, and the lines of constant reactance are drawn as arcs that curve across the chart’s surface.
Therefore, the curved lines (the arcs) on a Smith chart represent Points with constant reactance. All points that fall on the same arc have the same normalized inductive reactance (in the upper half of the chart) or the same normalized capacitive reactance (in the lower half of the chart).
