Thevenins Theorem, A linear two-terminal circuit can be replaced by an equivalent circuit consisting of a voltage source VTh in series with a resistor/impedance RTh/ZTh, where VTh is the open circuit voltage at the terminals and RTh/ZTh is the input or equivalent resistance/impedance at the terminals when the independent sources are turned off Formula to find load current for DC circuit is ...
To measure the input impedance over a complete spectrum of frequencies, use the following circuit: The input is a constant current source, its value set to 1 amp. As V= I * Z, and using 1 amp as shown for the current source, hence V=1*Z or V=Z. Hence measuring input voltage returns input impedance.
Ver 2427 E1.1 Analysis of Circuits (2014) E1.1 Circuit Analysis Problem Sheet 1 - Solutions 1. Circuit (a) is a parallel circuit: there are only two nodes and all four components are connected between them. Circuit (b) is a series circuit: each node is connected to exactly two components and the same current must ow through each. 2.
A graph of the parallel RL circuit impedance ZRL against frequency f for a given inductance and resistance For the parallel RL circuit, the impedance is a complex number and is determined as The applied voltage VT is the same across both the resistor and the inductor. The total current IT is divided into the two branch currents IL and IR:
A series LR circuit is shown below: If we consider the frequency response of this circuit we will see that it is a low pass filter. If we recall from section 3, the impedance of an inductor is: hence if the frequency is 0 (i.e. D.C.) then the impedance of the inductor is zero, i.e. short circuit. The equivalent D.C. circuit is shown below:
