2. Chapter 2.5: Series-Parallel AC Network

3. Series-Parallel AC Network • In general, when working with series-parallel ac network: Step 1: - Redraw the network, using blog impedance to combine obvious series and parallel element. - reduce the network to one that clearly reveal the fundamental structure of the system.

4. Series-Parallel AC Network (Cont…) Step 2 - Study the problem and make a brief mental of overall approach plan to use. - using this may result in time and energy saving shortcut. - some cases, a length may not necessary and maybe a single application of fundamental law of circuit analysis may result in the desired solution.

5. Series-Parallel AC Network (Cont…) Step 3 - After overall approach has been determined,consider each branch involved in your method independently before tying them together in series-parallel combinations. - In most cases, work back from the obvious series and parallel combinations to the source to determine the total impedance of the network. - The source current can then be determined, and the path back to specific unknowns can be defined.As you progress back to the source, continually define those unknowns that have not been lost in the reduction process

6. Series-Parallel AC Network (Cont…) Step 4 - When you have arrived at a solution check to see that it is reasonable by considering the magnitudes of the energy source and the elements in the circuit. - If not, either solve the network using another approach, or check over your work very carefully.
