Star-delta transformation is a useful technique for simplifying complex electrical networks. By applying the transformation formulas, we can convert a star-connected circuit into an equivalent delta-connected circuit, or vice versa. The problems and solutions presented in this report demonstrate the application of star-delta transformation in solving electrical circuit problems. Most textbook problems fall into three categories: After
