Reactive impedance
http://www.learningaboutelectronics.com/Articles/What-is-impedance.php WebApr 24, 2014 · When a circuit element has a purely imaginary impedance, like, an inductor or a capacitor, in a harmonic AC circuit, the current through these elements is out of phase of the voltage across them by 90 degrees. Now, power dissipated by a circuit element is simply V ⋅ I (the dot product of the two phasors).

WebThe impedance Z of a reactive load comprising resistance R and shunt reactance X is found from: 1 / Z = 1 / R + 1 / jX. Converting to the equivalent admittance Y comprising … WebCalculation of Total Current and Total Impedance. There are two strategies for calculating the total current and total impedance. First, we could calculate total impedance from all the individual impedances in parallel (Z Total = 1/ (1/Z R + 1/Z L + 1/Z C ), and then calculate total current by dividing source voltage by total impedance (I=E/Z).
Web16 hours ago · We only need to eliminate the reactive component from the equivalent series capacitor (C S). The reactance of C S = 6.47 pF is about -j24.12 Ω at 1 GHz. We can use a series inductor of 3.84 nH to produce a reactance of about +j24.12 Ω. This series inductor cancels the reactance of C S, leaving us with a purely resistive impedance of 20 Ω ...

Impedance can be represented as a complex number, with the same units as resistance, for which the SI unit is the ohm (Ω). See more In electrical engineering, impedance is the opposition to alternating current presented by the combined effect of resistance and reactance in a circuit. Quantitatively, the impedance of a two-terminal See more Perhaps the earliest use of complex numbers in circuit analysis was by Johann Victor Wietlisbach in 1879 in analysing the Maxwell bridge. Wietlisbach avoided using differential equations by expressing AC currents and voltages as exponential functions See more To simplify calculations, sinusoidal voltage and current waves are commonly represented as complex-valued functions of time denoted as $${\displaystyle V}$$ and See more Impedance defined in terms of jω can strictly be applied only to circuits that are driven with a steady-state AC signal.
