The image shows a circuit diagram of an AC source connected to a transformer. The transformer has a turns ratio of \( N_1/N_2 = 2.70 \), a source resistor \( R_S \), and a load resistor \( R_L \). ### Diagram Details: - **AC Source (\(\Delta V_S\))**: The source provides an rms voltage of 86.0 V. - **Transformer**: Consists of two coils, primary (\(N_1\)) and secondary (\(N_2\)) with a turns ratio of 2.70. - **Load Resistor (\(R_L\))**: Has a resistance of 48.0 \(\Omega\). - **Voltmeter**: Measures an rms voltage of 26.0 V across the load resistor \(R_L\). ### Problem Statement: 1. **(a) Calculation Task**: Determine the value of the source resistor \( R_S \) in ohms (\(\Omega\)). - **Input Box with Incorrect Output**: 350 \(\Omega\) with a wrong answer indication. - **Hints Provided**: - Relationship between the rms voltage across secondary and primary coil. - Power delivery comparison between primary and load resistor. - Voltage relationships on the primary side. 2. **(b) What If Scenario**: If the turns ratio is increased to 3.00, determine the source resistance \( R_S \) in ohms (\(\Omega\)) needed to deliver the same power to the load. - **Input Box with Incorrect Output**: 432 \(\Omega\) with a wrong answer indication. - **Hints Provided**: - Modify previous work to account for the new turns ratio in order to maintain the same power delivery. This image provides a detailed circuit schematic and a problem scenario that involves understanding transformer behavior and electrical power relationships, aimed at educational purposes in Physics or Electrical Engineering courses.
