Impedance and Admittance

The impedance Z of a circuit is the ratio of the phasor voltage V to the phasor current I, measured in ohms.



In some ways, you could say that the impedance acts the same as the resistance in a circuit, but not completely.


The admittance Y is the reciprocal of impedance, measured in siemens.







Resistors, capacitors, and inductors are the three elements that cause impedance. Though you have to convert the capacitance C and the inductance L to get their equivalent impedances Z, by applying these formulas:
