Question
**Title: Determining Voltage in a Complex Circuit Using Delta-Wye Conversion** **Introduction:** In this tutorial, we will explore how to determine the voltage in a given electrical circuit. The circuit consists of several resistors, a voltage source, and an unknown voltage \( V \). We'll utilize the Delta-Wye (Δ-Y) conversion method to simplify the complex network of resistors. **Circuit Diagram:** - **Voltage Source:** 60V positioned on the left. - **Resistors:** - A 12Ω resistor connected in series with the voltage source. - Three resistors (15Ω, 10Ω, and 20Ω) arranged in a triangle, forming a Delta configuration at the top of the diagram. - A 30Ω resistor connected vertically, positioned between the Delta configuration and the reference voltage \( V \). - A 16Ω resistor and another 30Ω resistor connected in parallel below the triangle. These are followed by a 20Ω resistor in parallel on the right. **Objective:** Our goal is to find the voltage \( V \) using the Delta-Wye conversion method. **Delta-Wye Conversion:** 1. **Identify Delta Configuration:** - The resistors 15Ω, 10Ω, and 20Ω form a Delta configuration. 2. **Convert Delta to Wye:** - Use Delta-Wye formulas to convert these resistors into an equivalent Wye configuration. 3. **Simplify the Circuit:** - Once converted, recalculate total resistance and solve for the unknown voltage \( V \). **Conclusion:** By transforming the circuit with Delta-Wye conversion, we simplify complex networks into manageable series and parallel combinations, making it easier to find unknown parameters such as voltage \( V \). This method is essential for analyzing circuits that cannot be simplified by direct series or parallel combinations due to the topology of the connections.
