The required passband gain is -: PageProblem We will use ejerciciis initial conditions to evaluate the constants A and 5. Next, find the response to the dc current source acting alone: Consequently, the capacitor is replaced by an open circuit. Here is shows the circuit that is used to detennine R t.

Because the only input to this circuit is the constant voltage of the voltage source, all of the element currents and voltages, including the inductor current, will have constant values. A data entry error was made while doing the computer analysis.

The are all okay. All the element currents and voltages will again have constant values, but probably different constant values than they had before the switch closed. Then a maximum power will be dissipated in resistor R when: The energy stored in the inductor instantaneously dissipates in the spark.


Parallel resistors, then source transformation at left: We conclude that this circuit cannot produce a phase shift equal to The given mesh currents are not correct. Initial and Final Value Theorems P There is no current in the horizontal resistor and v 0 oo is equal to the voltage across the vertical resistor.

Design Using Operational Amplifier P6. The resistor in Box B will be shorted, draw no current, and dissipate no power. The power received by the element is the negative of the power delivered by the element, W. A plot of the output of the VCCS versus the input is shown below.

Ejercicios Resueltos de Thevenin y Norton

Phasor Diagrams P Imaginary P Solving for v out: This data does seem reasonable. The required capacitor is calculated as X. Ejerciciios element is indeed linear. Before the switch closes, the circuit will be at steady state.

In Figure bmesh current i 2 is equal to thevdnin negative of the current source current. Express Ii and I 2 as: The values of A and B are determined from the steady state responses of this circuit before and after the input changes value.

In Figure cmesh current i 2 is equal to the current in the open circuit. VP Initial value of h 5: Thus inductor current is Nio 3 4 3 i L t — 2 e?

Because the circuit is at steady state, the value of the capacitor voltage will be constant. Using the initial conditions: Both coils were described as having the dotted end at the top. The power supplied by element B is 12 W. Both inputs are constant so ejercifios capacitor will act like an open circuit at steady state, and the inductor will act like a short circuit. There is no current in the horizontal resistor due to the open circuit.


Also, the nodes have been identified and labeled in anticipation of writing node equations. The voltage across that open circuit is the steady-state capacitor voltage, v 0 oo. KCL at the top node of fU gives: The mesh currents cannot be correct. Kirchhoff s Laws Using Phasors P The power dissipated in the resistors is excessive.

Figure c shows the circuit from Figure 4. A half watt resistor can’t absorb this ejervicios power. VP We need to check the values of the inductor current at the ends of the intervals.

To determine the value of the Thevenin resistance, R t h, first replace nirton 24 V voltage source noorton a 0 V voltage source, i.

Initial value of Vc s: Maximum Power Transfer Theorem Pll.

The current in the 3 Q resistor is zero because of the short circuit. The Power Superposition Principle Pll.

Solving for v 0: From the output file: Consequently, v o 0 is equal to the voltage across the vertical resistor, which is equal to the voltage source voltage.
