We will show several different ways of finding the node voltages and branch currents. First we will use the bias display markers provided by Capture. 

We will run the analysis to calculate all node voltages and all branch currents. Select PSpice and then Run from the Capture menus ... 

Clicking this button will toggle the display of branch currents on and off. Click the i I button to hide the branch currents. 

Now that we know all of the node voltages, we would like to display the branch currents. First, hide the node voltages by clicking the LEFT mouse button on the V button OD. The voltages should no longer be displayed ... 

Branch currents can be hidden using a procedure similar to what we used to hide node voltages. Click the LEFT mouse button on the text 7.954/114 at the bottom of the screen. It will become highlighted in pink ... 

Suppose that we have hidden a number of the branch currents, and we now wish to display one of the hidden currents. Displaying hidden branch currents is a little different than displaying hidden node voltages. Node voltages are...

The Records Conservation Section, staffed with 20 persons, of the Administration and the Technical Services Branch currently provide conservation and restoration services for paper materials to the Public Archives and National Library of Canada. Studies, both within and without the Public Archives, indicate the present collection is deteriorating more rapidly than the Records Conservation Section can restore it. Moreover, the collections are growing at increased rates, and the stability of materials to be acquired is projected as no better than materials already in the collection. 

Since a tree in a graph contains no loops, all the tree branch currents depend on the link currents. In other words, all the tree branch currents can be expressed in terms of the link currents. Assuming the number of branches in a circuit is B, there will be B-(N-l) link currents, which are independent. Therefore, B-(N-l) independent equations are needed to analyze the circuit. For example, Figure 232b needs three independent current equations. 

If the harmonic content of the applied voltage is known in terms of magnitudes and phase shifts of the components, then the circuit can be solved for each frequency. The result for each branch current or voltage will be the sum of all their harmonic components plus their fundamentals. 

In the circuit of Fig. 1, the ratio of the branch currents is fixed because of the permanent hole in the shield. The inductance switch, however, is a device that provides control over a hole in the shield plane. In other words, the switch can establish a virtual hole in the diamagnetic barrier, and remove it again. This is accomplished by destroying the superconductivity of a section of the ground plane, thereby eliminating the Meissner effect in that section. Circuit conductors passing over this artificial hole thus have extremely high relative inductance in that area. 

When sufficient current is applied to the control element, the adjacent area of the tin shield becomes resistive (Fig. 2b), destroying the Meissner effect in that area. In this state, a window is formed the tin no longer serves as a shield to the branch conductor, and the magnetic flux associated with the branch current can penetrate the artificial hole, resulting in a large A< /Az. 

The impedance of a parallel RC circuit is always less than die resistance R or capacitive reactance Xc of the individnal branches. The relative valnes of Xc and R determine how capacitive or resistive the circnit line current is. The one that is the smallest and therefore allows more branch current to flow is the determining factor. Thus if Xc is smaller than R , the cnricnt in the capacitive branch is larger than the cnrrcnt in the resistive branch, and the line ciurent tends to be more capacitive (Fignre 16.8) (Jainwen et al., 2006). 

When a sinusoidal source is applied to a stable linear circuit all of the steady-state node voltages and branch currents in the circuit will be sinusoids having the same frequency as the input. A sinusoidal input signal produces a sinusoidal steady-state output (response). The steady-state response of a given node voltage or branch current, however, may have different ampU-...

We first examine an operational simulation. Consider the doubly terminated ladder network shown in Fig. 7.122. This network represents a low-pass filter that has been frequency denormalized (frequency scaled up to the frequencies of interest). Interior node voltage V) and branch currents D and I2 have been identihed in the hgure. The hrst step in obtaining the operational simulation of this network is to write the network equations using Kirchhoff s and Ohm s laws. The equations are...
