Impedance in rectangular form
The impedance of a circuit element can be defined as the ratio of the phasor voltage across the element to the phasor current through the element, as determined by the relative amplitudes and phases of the voltage and current. This is identical to the definition from Ohm's law given above, … Zobacz więcej 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 Zobacz więcej 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 Zobacz więcej Resistor The impedance of an ideal resistor is purely real and is called resistive impedance: $${\displaystyle \ Z_{R}=R}$$ In this case, the voltage and current waveforms are proportional and in phase. Inductor and … Zobacz więcej Resistance and reactance together determine the magnitude and phase of the impedance through the following relations: $${\displaystyle {\begin{aligned} Z &={\sqrt {ZZ^{*}}}={\sqrt {R^{2}+X^{2}}}\\\theta &=\arctan {\left({\frac {X}{R}}\right)}\end{aligned}}}$$ In many applications, the relative phase of the voltage and current is not critical so only the … Zobacz więcej In addition to resistance as seen in DC circuits, impedance in AC circuits includes the effects of the induction of voltages in conductors by the Zobacz więcej To simplify calculations, sinusoidal voltage and current waves are commonly represented as complex-valued functions of time denoted as $${\displaystyle V}$$ and $${\displaystyle I}$$. The … Zobacz więcej Impedance defined in terms of jω can strictly be applied only to circuits that are driven with a steady-state AC signal. The concept of … Zobacz więcej Witrynaelectrical impedance, measure of the total opposition that a circuit or a part of a circuit presents to electric current. Impedance includes both resistance and reactance. The …
