WebImpedance is the amount of resistance that a component offers to current flow in a circuit at a specific frequency. In this article, we'll talk about how impedance is similar to and … WebImpedance is the reciprocal of mobility. If the potential and flow quantities are measured at the same point then impedance is referred as driving point impedance; otherwise, transfer impedance. Resistance - the real part of an impedance. Reactance - the imaginary part of an impedance.
