STAR DELTA TRANSFORMATION ( NEED NEAT HANDWRITTEN SOLUTION ONLY OTHERWISE DOWNVOTE).

**Problem Statement:** Q2. Apply star-delta transformation wherever necessary to determine the following: a. The total resistance as seen from terminals \(ab\). b. Determine the Total Current \(I\). **Circuit Diagram Explanation:** The provided circuit diagram consists of multiple resistors connected in a combination of series and parallel configurations: - Terminals \(a\), \(b\), \(c\), and intermediate nodes \(m\) and \(n\) are labeled in the circuit. - The circuit is powered by a 120 V voltage source connected across terminals \(a\) and \(b\). - Resistor values are as follows: - Between terminal \(a\) and node \(m\): \(12.5 \, \Omega\) - Between node \(m\) and terminal \(b\): \(15 \, \Omega\) - Between terminal \(a\) and node \(n\): \(10 \, \Omega\) - Between node \(n\) and terminal \(b\): \(20 \, \Omega\) - Between nodes \(m\) and \(n\): \(5 \, \Omega\) - Across terminal \(a\) and \(b\): \(30 \, \Omega\) **Goal:** 1. Determine the total resistance of the circuit as seen from terminals \(ab\). 2. Calculate the total current \(I\) flowing through the circuit by applying the concepts of star-delta transformation where necessary. **Steps to Solve:** 1. **Identify Opportunities for Star-Delta Transformation:** - Analyze the circuit to identify areas where star-delta transformations can simplify the combination of resistors. 2. **Simplify the Circuit:** - Apply the star-delta transformation to the identified parts of the circuit. - Combine series and parallel resistances step-by-step until the total equivalent resistance is found. 3. **Calculate Total Resistance:** - Once the simplified circuit is obtained, total resistance \(R_{total}\) can be calculated as seen from terminals \(ab\). 4. **Calculate Total Current:** - Using Ohm's Law \(I = \frac{V}{R_{total}}\), calculate the total current \(I\). **Discussion:** Detailed steps for calculations will be provided, including star-delta transformation equations and intermediate steps for combining resistances. Each step will clarify how the complex
