The points P, Q, and R shown on the Smith chart (normalized impedance chart) in the following figure represent:

1. P: Open Circuit, Q: Short Circuit, R: Matched Load
2. P: Open Circuit, Q: Matched Load, R: Short Circuit
3. P: Short Circuit, Q: Matched Load, R: Open Circuit
4. P: Short Circuit, Q: Open Circuit, R: Matched Load

Correct answer: P: Short Circuit, Q: Matched Load, R: Open Circuit

Solution

The correct option identifies P as a short circuit, which is represented at the center of the Smith chart, Q as a matched load located on the 1.0 normalized impedance circle, and R as an open circuit, positioned at the edge of the chart. This arrangement accurately reflects the characteristics of each impedance type on the Smith chart.
