Abstract— on this experiment, analysis of resistive network by series-parallel circuits, the students will demonstrate the characteristics of series-parallel circuits by measuring and verifying the calculations of the resistance, voltage and current associated with the different resistive components of a series – parallel circuit. On this experiment, the students will also demonstrate the principle of basic electric circuit Law called Ohm’s Law as well as the use of basic principles involved in series, parallel and series-parallel. This experiment discusses about the use of the Ohm’s Law and its applications on a real circuit. With the use of a circuit simulation, the group verified the values obtain through computation.

Introduction
Equation 1: Delta -Wye Transformation
Equation 1: Delta -Wye Transformation
The experiment is all about Delta-Wye and Wye-Delta Transformation. Before getting into the experiment, one should take note about the theories behind this experiment. Electric circuit may contain networks that are neither in series nor in parallel, making it difficult to analyse them using the previous techniques. In such cases, certain parts of the circuit are replaced with by their three terminal equivalents. The three terminal network, delta and wye, is said to be equivalent to each other if the corresponding resistances measured between the pair of terminals are equal. The two networks are then identical and equivalent to each other (see Figure 1).

A transformation formula is based on the concept that if the two connections are equivalent then the resistances seen across
