Impedance and admittance

So, I need to calculate the complex impedance, the impedance and admittance of a capacitor with : C = 33 nF f = 100 Hz and knowing that X = -1/2*pifC. So far I figured out that the pulsation is ω = 6,28 * 10^2 and that X = -48,2532 * 10^-3 [Ohm]. Right now I need to calculate the impedance Z.

Impedance and admittance. Impedance Z relates the voltage and current described in the s-domain when initial conditions are set to 0. The following algebraic form of the i-v relationship describes impedance in the s-domain: V(s) = Z(s)I(s) Admittance Y is the reciprocal of the impedance; it’s useful when you’re analyzing parallel circuits:Impedance, denoted Z , is an expression of the opposition that an electronic component, circuit, or system offers to alternating and/or direct electric current .Impedance is a vector (two-dimensional)quantity consisting of two independent scalar (one-dimensional) phenomena: resistance and reactance .Jul 16, 2016 · Admittance, Y, is the reciprocal of impedance. We define Y as, Y = 1/Z. Y = G + jB. G is the conductance and B is the susceptance. The synonymous unit of Admittance is mho, and the symbol ℧ (an upside-down uppercase omega Ω), are also in common use. Normally we take impedance for series circuit to express voltage in terms of current. Depending on the nature of the reactance component of the impedance (whether predominantly inductive or capacitive), the alternating current either lags or leads the voltage. The reciprocal of the impedance, 1/Z, is called the admittance and is expressed in terms of the unit of conductance, the mho unit (ohm spelled backward).Impedance and Admittance Control are two well-known controllers to accomplish the same goal: the regulation of the mechanical impedance of manipulators interacting dynamically with the environment ...Impedance and Admittance Inverters 871 g0 g3 g2 g1 Zin ZL z1 (a) g0 g1 K = 1 K = 1 g2 g3 Zin z3b z2b z1b (b) g0 K = 1Acoustic Impedance and Admittance: Measurement of Middle Ear [Feldman, Alan S. and Laura A.

Mechanical impedance is the inverse of mechanical admittance or mobility. The mechanical impedance is a function of the frequency of the applied force and can vary greatly over frequency. At resonance frequencies, the mechanical impedance will be lower, meaning less force is needed to cause a structure to move at a given velocity.

The admittance of the whole circuit is 1 R ⋅ [ 2 − ja 3 − 2ja]. Multiply top and bottom by the conjugate of the denominator to obtain 1 R ⋅ [6 + 2a2 + ja 9 + 4a2]. The reciprocal of impedance is admittance, whose SI unit is the siemens, formerly called mho. Instruments used to measure the electrical impedance are called impedance analyzers. History.
