Вопрос 263

What coordinate system is often used to display the phase angle of a circuit containing resistance, inductive, and/or capacitive reactance?

  1. Maidenhead grid
  2. Faraday grid
  3. Elliptical coordinates
  4. Polar coordinatesПравильный ответ

Объяснение

Polar coordinates express an impedance as a magnitude and an angle, so the phase angle appears directly as one of the two numbers. The Maidenhead grid is a geographic locator system and has nothing to do with circuit analysis.
