Question

Please show the calculations to find these values from the cicuit

The image is a table with three columns and two rows. The headers for the columns are as follows: 1. First Column: "Reactive Power Delivered by the Generator, VAR" 2. Second Column: "Real Power Absorbed by the Load, W" 3. Third Column: "Reactive Power Absorbed by the Load, VAR" The second row below these headers is empty, indicating that the table might be awaiting data input related to electrical power systems. The table is likely used for documenting power measurements, with real power measured in watts (W) and reactive power measured in volt-amperes reactive (VAR).

The diagram shown is a representation of an electrical circuit simulation used to analyze power loss and voltage in a system operating at 60 Hz. The components and connections in the diagram can be divided into the following sections: 1. **Voltage Source**: - The system is powered by a voltage source of 480 V, depicted at the left side of the diagram. 2. **Line Current Measurement**: - The line current entering the circuit is labeled, and its value is used in calculations further in the diagram. 3. **Impedance and Load**: - The circuit includes a series impedance of \(0.18 + j0.24\) Ohms followed by a load impedance of \(4 + j3\) Ohms. - The phasor measurements are marked, indicating the flow of current and voltage drop across these impedances. 4. **Power Loss Calculation**: - A block is designed to compute power loss (\(P_{\text{Loss}}\)) in the circuit. It utilizes the formula: \[ P_{\text{Loss}} = I^2 \times R \] - Here, \(I\) (current) is squared and multiplied by the resistance value \(R = 0.18\) Ohms. - The power loss calculated is labeled as 1483 W in the block. 5. **Current and Load Voltage Display**: - The current's value is displayed as 90.76 A. - The load voltage is calculated and shown as 453.8 V with a phase angle of -0.9101 radians. 6. **Simulation Configuration**: - The diagram includes a "powergui" block, which indicates that the simulation is set to analyze the circuit using MATLAB/Simulink at a frequency of 60 Hz, using phasor representation. The diagram integrates both the theoretical and practical aspects of analyzing AC circuits, focusing particularly on power loss and voltage across the load, valuable for educational purposes in electrical engineering.
