Transforming an Impedance to an Admittance It is often useful to find the admittance, the inverse of a given impedance. y = 1/zFeb 17, 2014. Impedance Mean Negative. On the other hand, the coil has a positive reactance because coil current is lags the coil voltage by 90 degree. As for impedance vs admittance, sometimes the math is easier when we use admittance instead of impedance. I assume you are talking about something such as, -jXc or -jXL? the negative is attached ...Impedance Formula. The mathematical symbol of impedance is Z, and the unit of measurement is the ohm. It is the superset of both resistance and reactance combined. In phasor terms, impedance Z is characterized as a summation of resistance R and reactance X as: X = R + j X. Where reactance X is the summation of iInductive reactance X.Admittance is measured in (guess what?) the unit of Siemens, and its symbol is “Y”. Like impedance, admittance is a complex quantity rather than scalar. Again, we see a certain logic to the naming of this new term: while impedance is a measure of how much alternating current is impeded in a circuit, admittance is a measure of how much ...
