The image displays an electrical circuit diagram with four parallel loads connected across an AC source. The source voltage is \( E = 50 \, V \angle 60^\circ \). ### Components: - **Source:** - Voltage: \( 50 \, V \) - Phase angle: \( 60^\circ \) - **Loads:** - **Load 1:** - Inductive reactance: \( 100 \, VAR (L) \) - Real power: \( 200 \, W \) - **Load 2:** - Inductive reactance: \( 50 \, VAR (L) \) - Real power: \( 100 \, W \) - **Load 3:** - Capacitive reactance: \( 200 \, VAR (C) \) - Real power: \( 0 \, W \) - **Load 4:** - Capacitive reactance: \( 400 \, VAR (C) \) - Real power: \( 50 \, W \) ### Current: - The current flowing through the circuit is depicted as \( I_s \), flowing from the AC source through the parallel loads. ### Description: The circuit illustrates power distribution among multiple parallel loads with specified inductive and capacitive reactive power along with the real power component. This setup is typical for analyzing power factor and reactive power management in AC circuits. Each load has a unique combination of real and reactive power, highlighting the phase difference influence in electrical systems.
