**Educational Content on Three-Phase Circuit Analysis** --- **Introduction:** Welcome to this educational module on the analysis of balanced three-phase circuits. Understanding such systems is crucial for grasping the fundamentals of electrical engineering, particularly in power distribution. --- **Problem Statement:** **Required Information:** Consider the given circuit diagram. In this balanced three-phase system: - \( R_w = 0 \) - The line-to-neutral voltage \( V_{an} \) is given as \( 208 \angle 0^\circ \) volts - A positive phase sequence applies Your task is to calculate all phase and line currents, as well as all phase and line voltages, given that \( Z_p \) equals \( (115.0 - j63.0) \, \Omega \). **Instructions:** Report your answers ensuring that: - All magnitudes are positive - All angles are within the range of negative 360 degrees to positive 360 degrees --- **Circuit Explanation:** The circuit diagram features: - Three-phase voltage sources labeled \( V_{cn}, V_{bn}, \) and \( V_{an} \), connected in a wye (Y) configuration. - Each phase is connected through line impedances \( R_w \), assumed to be zero in this scenario, indicating negligible line resistance. - Load impedances \( Z_p \) are connected in parallel across each phase and are characterized by both resistive and reactive components. **Objective:** The goal is to systematically determine the electrical parameters of the circuit under balanced conditions. This entails using complex power formulas and phasor mathematics to derive current and voltage across different parts of the circuit. **Example Calculation Approach:** 1. **Calculate line current \( I_a \):** Using Ohm's Law for AC circuits: \[ I_a = \frac{V_{an}}{Z_p} \] Substituting the given values, perform the complex division to determine \( I_a \). 2. **Determine phase and line voltages:** Use the relationships inherent in balanced systems and phasor transformations: - Line-to-line voltage: \( V_{ab} = V_{an} \sqrt{3} \angle (30^\circ) \) - Verify equality in magnitudes due to balance. 3. **Checking phase currents:** Equally measure \( I_b \) and \( I
