Impedance, denoted Z, is an expression of the opposition that an electronic component, circuit, or system offers to alternating and/or direct electric current.Impedance is a vector (two-dimensional)quantity consisting of two independent scalar (one-dimensional) phenomena: resistance and reactance.
Impedance is defined as the frequency domain ratio of the voltage to the current. In other words, it is the voltageâcurrent ratio for a single complex exponential at a particular frequency Ï. In general, impedance will be a complex number, with the same units as resistance, for which the SI unit is the ohm (Ï). For a sinusoidal current or voltage input, the polar form of the complex impedance relates the amplitude and phase of the voltage and current.
