At frequency below resonant frequency i.e. You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +… If one of the parallel paths is broken, current will continue to flow in all the other paths. Figure 2: Constant parallel resistance maps as a circle. Admittance is the inverse of impedance. electrical impedance, measure of the total opposition that a circuit or a part of a circuit presents to electric current. ϕ = tan-1 (X/R) Admittance. This is the only way to calculate the total impedance of a circuit in parallel that includes both resistance and reactance. 1. I want to calculate value of rs. A Bode plot is a graph plotting waveform amplitude or phase on one axis and frequency on the other. Then the formula of the impedance of RC circuit is, \small {\color{Blue} … The impedance (Z) of a parallel RC circuit is similar to that of a parallel RL circuit and is summarized as follows: Impedance can be calculated directly from the resistance and capacitive reactance values using the equation.
