### Circuit Diagram Explanation This image depicts an electrical circuit featuring two resistors and an inductor connected in series. Below is a detailed description: - **Resistors (R1 and R2):** - Each resistor has a resistance of 1 kilo-ohm (1 kΩ). - **Inductor (L1):** - The inductor has an inductance of 13.2 henries (H). - **Power Source:** - The circuit is powered by an alternating current (AC) source with a voltage of 120 volts (VAC) and a frequency of 60 hertz (Hz). ### Key Components and Their Functions: 1. **Resistors (R1 and R2):** - Resistors are passive components that oppose the flow of electric current, causing a voltage drop. In this circuit, R1 and R2 help control the current flowing through the circuit. 2. **Inductor (L1):** - An inductor stores energy in a magnetic field when electric current passes through it. L1’s high inductance value of 13.2 H suggests it plays a significant role in opposing changes in current flow, affecting the circuit’s impedance and phase shift characteristics. 3. **AC Power Source:** - The AC power source supplies the circuit with an oscillating voltage that follows a sinusoidal waveform. Given its specified frequency of 60 Hz, this aligns with the standard power supply frequency in North America. ### Overall Functionality: This circuit could be used for educational purposes to demonstrate the behavior of AC circuits containing resistive and inductive elements, focusing on impedance and phase relationships between voltage and current.
