Question 258

Which of the following represents a pure inductive reactance in polar coordinates?

  1. A positive 45 degree phase angle
  2. A negative 45 degree phase angle
  3. A positive 90 degree phase angleBonne réponse
  4. A negative 90 degree phase angle

Explication

A pure inductance has no resistive component, so its impedance vector lies entirely along the positive imaginary direction. That corresponds to an angle of +90 degrees; −90 degrees would be pure capacitive reactance.
