Frage 261

What does the impedance 50 - j25 ohms represent?

  1. 50 ohms resistance in series with 25 ohms inductive reactance
  2. 50 ohms resistance in series with 25 ohms capacitive reactanceRichtige Antwort
  3. 25 ohms resistance in series with 50 ohms inductive reactance
  4. 25 ohms resistance in series with 50 ohms capacitive reactance

Erklärung

The real term is the series resistance and the imaginary term is the series reactance. A minus sign on the j term marks the reactance as capacitive, so this is 50 Ω of resistance with 25 Ω of capacitive reactance.
