How is impedance in polar form converted to an equivalent admittance?

  1. Take the reciprocal of the angle and change the sign of the magnitude
  2. Take the reciprocal of the magnitude and change the sign of the angleRespuesta correcta
  3. Take the square root of the magnitude and add 180 degrees to the angle
  4. Square the magnitude and subtract 90 degrees from the angle

Explicación

Admittance is the reciprocal of impedance, and dividing one by a polar quantity inverts the magnitude while negating the angle. So an impedance of magnitude M at angle θ becomes an admittance of magnitude 1/M at angle −θ.
