Search the history of over billion web pages on the Internet. Page 42, line The answer should be v 0 l. PageProblem P8. PageProblem P. PageProblem Partial t in exponent: The power received by the element is the negative of the power delivered by the resuelots, W.
The power supplied by the element is the negative of the power delivered to the element, W. Assuming no more energy is delivered to the battery after 5 hours battery is fully charged. The sum of the powers absorbed by each branch are: VP Notice that the element voltage and current of some branches do not adhere to the passive convention. Design Problems DP The voltage may be as large as 20 1. The element needs to be able to absorb 25 V 0. A Grade B element is adequate, but without margin for error.
Specify a Grade B device if you trust the estimates thevenib the maximum voltage and thevrnin and a Grade A device otherwise.
Chapter 2 – Circuit Elements Exercises Ex. The power supplied by the dependent source is For example, ejercicis the current from 2 A to 4 A does not double the voltage, ffence, the property of homogeneity is not satisfied.
The slope of the line is 0. The element is indeed linear. The slope of the ejecricios is Hence, the property of homogeneity is not satisfied. The element is not linear. Section Resistors P2.
The power absorbed by i? The voltage source supplies W. Current source supplies W. The voltage source delivers -6 W. Q kQ l.

Notice that the ammeter measures -i s rather than i s. A half watt resistor can’t absorb this much power. You should not try another resistor. These conditions cannot satisfied simultaneously. The power supplied by element B is 12 W.
KCL at node a: The current in both R, and R 1 will be 1 A. Nofton vertical 1 Q resistor is equivalent to a 2 Q resistor connected in parallel with series 1 Q resistors: Reported value was correct. Solving the three above equations yields: Reported values were incorrect. The given values of i a and ib are not correct. Design Problems DP 1? Therefore the design is complete.
That is, Ri is an open circuit. Apply KCL at node a. Apply KVL to the supermesh: Notice that this is a node voltage.
From the output file: SP The PSpice schematic after running the simulation: The PSpice output file: However this current is directed from right to left in the 2 Q resistor while the current i is directed from left to right. They are not correct. Therefore, it is indeed possible that two of the resistances are 10 kQ and the other resistance is 5 kQ.
KVL is not satilied for the bottom, left mesh so the computer analysis is not correct.
The power dissipated in the resistors is excessive. Most of the power from the supply is dissipated in the resistors, not the display. Apply the voltage division principle in the left circuit to get: Source transformation at left; series resistors at right: Parallel resistors, then source transformation at left: Let 4 be the part of i due to the 30 mA current source.

Let A be the part of i due to the 15 V voltage source. Comparing e to Figure P5. Ejercicioss that v oc is the node voltage at node a. Express the ejerciciios voltage of the dependent source as a function of the node voltage: The slope of the plot is equal to the negative reciprocal of the Thevenin resistance, so 1 0 – 0.
Box B is therefore warmer than Resueltls A. If you short the terminals of each box, the resistor in Box A will draw 1 amp and dissipate 1 watt. The resistor in Box B will be shorted, draw no current, and dissipate no power. Then Box A will warm up and Box B will cool off. Figure a shows the circuit from Figure 5. Also, the meshes have been identified and labeled in anticipation of writing mesh equations. In Figure amesh current h is equal to the current in the short circuit.

To determine the value of the Thevenin resistance, R tfirst replace the 10 V voltage source by a 0 V voltage source, i. Next, connect a current source across the tenninals of the circuit and then label the voltage across that current source as shown in Figure b. In Figure bmesh current i 2 is equal to the negative of the current source current. To determine the value of the open circuit voltage, v ocwe connect an open circuit across the terminals of the circuit and then calculate the value of the voltage across that open circuit.
Figure c shows the circuit from Figure 4. In Figure cmesh current i 2 is equal to the current in the open circuit. Figure a shows the circuit from Figure 4.
Also, the nodes have been identified and labeled in anticipation of writing node equations. The controlling voltage of the VCCS, v ais equal to the node voltage at node 2, i.
The voltage at node 3 is equal to the voltage across a short, i. To determine the value of the Thevenin resistance, R t h, first replace the 24 V voltage source by a 0 V voltage source, i. Next, connect a current source circuit across the terminals of the circuit and then label the voltage across that current source as shown in Figure b. Let vi, v 2 and V 3 denote the node voltages at nodes 1, 2 and 3, respectively.
The voltage at node 3 is equal to the voltage across the current source, i. Apply KCL at node 2 to get v. Figure c shows the circuit from Figure P 4. In Figure cnode voltage vi is equal to the negative of the voltage source voltage.
The voltage at node 3 is equal to the open circuit voltage, i. Maximum Power Transfer P5. Then a maximum power will be dissipated in resistor R when: The current in the 3 Q resistor is zero because of the short circuit. Apply KCL at the top-left node to get so Next 0. That is, the slope of the line is equal to -1 times the Thevenin resistance and the “v – intercept” is equal to the open circuit voltage. That is, the slope of the line is equal to -1 times the Thevenin resistance and the “v – intercept” is equal to the: DP The slope of the graph is positive so the Thevenin resistance is negative.
That is, the slope of the line is equal to the Thevenin impedance and the “v – intercept” is equal to the open circuit voltage.
