Ideal resistor is a two-terminal electronic component that produces across its terminals a voltage which is proportional to the electric current passing through the component in accordance with the Ohm's law: U = IR.

It is assumed that ideal resistor has frequency-independent purely real impedance: ZR)f( = R .

Model of ideal Resistor

Page 17: Elena Smith Vladislav Shteeman Department of Electrical and Electronic Engineering ORT Braude College.

Ideal capacitor is a two-terminal electronic component that characterized by a single constant value, capacitance, which is measured in farads. This is the ratio of the electric charge on each conductor plate to the potential difference between them: C = q/U.

It is assumed that capacitor is a circuit opening for DC and has purely imaginary frequency-dependent impedance ZC)f( = -i/)2πfC( .

Model of ideal Capacitor

Page 18: Elena Smith Vladislav Shteeman Department of Electrical and Electronic Engineering ORT Braude College.

Ideal inductor (coil) is a two-terminal electronic component that can store energy in a magnetic field created by the electric current passing through it. A coil's ability to store magnetic energy is measured by its inductance (in units of Henries). Typically, an inductor is a conducting wire shaped as a coil, the loops helping to create a strong magnetic field inside the coil due to Faraday's Law of Induction: |ε|=N•|dФB/dt| (where |ε| is the magnitude of the electromotive force (in volts), N is the number of turns of wire and ФB is the magnetic flux (in Webers) through a single loop).

It is assumed that coil is a short circuit for DC and has purely imaginary frequency-dependent impedance : ZL)f( = i2πfL .

Model of ideal Coil

Page 19: Elena Smith Vladislav Shteeman Department of Electrical and Electronic Engineering ORT Braude College.

In sum up, for ideal components, Z)f( is purely real for R, and purely imaginary for C and L. For L, the phase of Z)f( is rotated by angle π/2 , while for C, it is rotated by angle - π/2.

Nevertheless, in any real passive component always present some physical factors (i.e. input-output contacts, interface contacts of different chemical materials inside the component etc), preventing it from functioning as an ideal one. In order to account for these factors and accurately predict the performances of the component under different operation conditions, the concept of equivalent circuits, representing a single real passive element as an array of different ideal passive elements was introduced. Thus, each true passive component has a complex impedance function, Z)f(, which can be decomposed onto the real and imaginary parts (active Re(Z)f(), and reactive Im(Z)f() parts).

Note that the same element can be represented by a number of equivalent circuits. Different equivalent circles reflect correctly different operation modes of the same component.

It can be shown that for the equivalent circle of resistor, the real part of the impedance, Re(Z)f(), has a form:

Impedance Z)f( characteristics of resistor )R = 150 kΩ, frequency range - 100Hz – 1MHz(. As one can see, the higher the frequency )even though 1MHz,the highest frequency applied, is NOT a high frequency(, the stronger the influence of the CR shunt and the lower the impedance, Z)f(.
