Abstract:
Formulas to convert the impedance parameters of a Constant Phase Element into an equivalent capacitor or inductor are provided, using the time constant associated with an additional resistance in the equivalent circuit. We justify the formulas and show the interpretation for both frequency domain impedance spectroscopy measurements and time domain transient charging current.

The process of source transformation in the frequency domain entails the conversion of a voltage source, positioned in series with an impedance, into a current source that is parallel to an impedance, or the other way around. It is essential to maintain the following relationships while transitioning from one source type to another.

RLC Series Circuits: Impedance
2.1K
When current flow is opposed in a DC or AC circuit, it is referred to as resistance or impedance, respectively. Impedance plays a key role in determining the performance of AC circuits. It is represented by Z, which is a combination of resistance and reactance, and depends upon the angular frequency, measured in ohms.
Thus, the magnitude of the impedance is given by the following equation,
Thus, the magnitude of the impedance is given by the following equation,
