Question
### Homework Assignment **Task:** 1. Complete parts a and d-g in the problem below: **Problem Statement for the Network of Fig. 16.73:** a. Find the total impedance “seen” by the source. ~~b. Using the results of part (a), find the total admittance.~~ c. ~~Sketch the admittance diagram for the parallel network.~~ d. Determine the source current \(I_S\). e. Calculate the current through the capacitive element \(I_C\). f. Write the sinusoidal expressions for the applied voltage and source current. g. What is the power factor of the network? Is it leading or lagging? Is this considered a capacitive or inductive configuration? **Diagram Description (Fig. 16.73):** - The circuit diagram shows a series and parallel connection. - Inductive reactance (\(X_L\)) of 40 Ω is connected in series with a resistor \(R_1\) of 220 Ω. - This series combination is connected in parallel with another branch consisting of a source voltage \(E\) (12 V, phase angle 20°) and a resistor \(R_2\) of 120 Ω. - A capacitive reactance (\(X_C\)) of 60 Ω is also connected parallel to the source. - Currents \(I_1\) and \(I_C\) are indicated in their respective components. **Note:** Please ensure to follow the steps methodically and verify your calculations as you work through each part of the problem.
