How is impedance in polar form converted to an equivalent admittance?
Pick an answer to check it.
Answer: B. Take the reciprocal of the magnitude and change the sign of the angle
Admittance is the reciprocal of impedance. In polar form, take the reciprocal of the magnitude and change the sign of the angle.
Tip: Flip the magnitude, flip the angle's sign.
