Given the circuit, as shown in Fig. 49, obtain the currents and voltages across each element. The values of impedances and the source are specified below. Use Delta to Star Conversion to solve the problem. At the bottom of this page, you have additional resources. If you click on HELP FILE FOR SOLUTION USING DELTA TO STAR CONVERSION button, a pop-up window opens and it is shown how this probe lm can be solved.
Replace the delta network, connected to connected to nodes a, b and c, by a star connected network, as shown in circuit in Fig. 53.
The steps for simplification are shown. You can enter your answers into the boxes of the applet shown below and check your answers.
The results obtained can be verified using Tellegen's theorem, as shown below.
