Then write a KCL equation at node 1. Embed Size px. Finally R1 is in parallel with the combination of the other resistors. Rearranging, this gives R1 4. WordPress Shortcode.
However, we know that the current through this source is 1 A flowing upward. Next we write a KVL equation around mesh 1: Referring to Figure 2.
Then we write a KVL equation for each mesh. Simplifying and solving, we find ix b First for the current source, we have: With the output shorted, the 5 A divides between the two resistances in parallel. Notice that the node voltage is the open-circuit voltage. Then write a KCL equation: The resulting circuits are: Thus, we find the open-circuit voltage and the short-circuit current.
Now, we find the short-circuit current: Then we combine the resistances in parallel. Thus the voltage across Req referenced positive at the bottom is 3.
Then from the original circuit we E2. Refer to Figure 2. Finally, by superposition we have iT E2. Then we combine resistances in series and parallel: With only the second source active, we have: Problems P2.
Finally Req3 and Req2 are in parallel and the overall equivalent resistance is Finally, the two parallel combinations are in series, and we have P2. The Clearly, for Req to be an integer, R must be an integer multiple of 5. R1 R2 Some other modes and resulting powers are: R1 operated separately from V yielding W R2 operated separately from V yielding W R1 in series with R2 operated from V yielding A second solution simply has the values of R1 and R2 interchanged.
The intermediate power settings are obtained by operating one of the elements from V resulting in powers of W and W. To turn a load on, we open the corresponding switch, and to turn a load off, we close the switch. After shorting terminals b and c, the equivalent Find a series or parallel combination of resistances. Combine them. Repeat until the network is reduced to a single resistance and a single source if possible.
Solve for the currents and voltages in the final circuit. Transfer results back along the chain of equivalent circuits, solving for more currents and voltages along the way. The method does not always work because some networks cannot be reduced sufficiently. Then, another method such as node voltages or mesh currents must be used. Then, we solve the simplified circuit and transfer information back along the chain of equivalents until we have found the desired results.
The resistance absorbs 36 W so power is conserved in the circuit. The current circulating counterclockwise in the right-hand loop is 3 A. The equivalent resistance for the parallel combination of R2 and the load is However, this would result in shorter battery life.
However, we reason that the resistance must be positive and discard the negative root. Thus, Rearranging, this gives R1 4. Maximum power is dissipated in R1 for iL Thus, R1 must be rated for at least Applying the voltage-division principle, we have Thus, we must place a resistor in parallel with the current source and the load.
Select a reference node and assign variables for the unknown node voltages. If the reference node is chosen at one end of an independent voltage source, one node voltage is known at the start, and fewer need to be computed. Write network equations. First, use KCL to write current equations for nodes and supernodes.
Write as many current equations as you can without using all of the nodes. Then if you do not have enough equations because of voltage sources connected between nodes, use KVL to write additional equations.
If the circuit contains dependent sources, find expressions for the controlling variables in terms of the node voltages. Substitute into the Put the equations into standard form and solve for the node voltages. Use the values found for the node voltages to calculate any other currents or voltages of interest. If the source is reversed, the algebraic signs are reversed in the I You just clipped your first slide! Clipping is a handy way to collect important slides you want to go back to later.
