WitrynaApparent power is a function of a circuit’s total impedance (Z). Since we’re dealing with scalar quantities for power calculation, any complex starting quantities such as voltage, current, and impedance must be represented by their polar magnitudes, not by real or imaginary rectangular components. WitrynaFrom our definition of a pure capacitor (i.e. one having no resistive component), we can say that the real impedance Z is zero.We see straightaway from equation (8.8) that the impedance is a function of frequency. The impedance of a capacitor is infinite when a DC voltage is applied (just put ru = 0 into equation (8.8)), while the imaginary …

WitrynaThe complex numerical nature of impedance is required to describe the fact that current and voltage can be out of phase. As you know, the simple limiting cases of impedance are wires (zero real and zero imaginary parts), resistance (positive real and zero imaginary), inductance (zero real and positive imaginary) and capacitance (zero real … WitrynaImpedance. Impedance (symbol Z ) is used in AC technology as a resistor in the current and voltage that are not in phase.
