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.

George Ohm— German physicist and Mathematician who gave the theory about electricity with the use of a galvanic circuit
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).

Figure 1: Delta Network, Wye Network (Left to Right)
A transformation formula is based on the concept that if the two connections are equivalent then the resistances seen across

    2. Compare and contrast a series and parallel circuit. Give at least one way that they are alike and one way that they are different. Both series and parallel circuits must have all the components of a complete circuit in order to work. These two circuits differ in the way the electrons are able to flow. In a series circuit the electrons flow in one direction and along one path only while in a parallel circuit the electrons may flow through different paths along any complete available circuit. In a parallel circuit more electrons will flow through the circuit as compared to the series circuit.…

    Georg Simon Ohm was the father of the Ohm. He was born in Bavaria and taught at a lot of universities and schools. While he was teaching at a bad school in Bamberg, he decided to prove that he was better than that by writing a geometry book. He later went onto, in 1827, to write and publish a book about a circuit that he had made called, ‘The Galvanic Circuit Investigated Mathematically.’ He put everything he knew about electricity into this book. He wrote about how the electromotive force at one point in the circuit is the product of the strength of the current and the resistance of that part in the circuit. His name is used for the SI unit ohm; to measure electrical resistance.…

Strings of holiday lights can be designed in one of two ways. In some strings of lights, each light is connected to the others along a single wire (in series). In others, each light is attached to its own wire (in parallel). Suppose a single light bulb burns out. How do you think this will affect lights that are strung along a single wire All the lights go out How will a single burned-out bulb affect the string of lights if each light is attached to its own wire Only that single light goes out Gizmo Warm-up The Circuits Gizmo shows a circuit board and a variety of components. Create a circuit with a battery, a light switch, a wire, and a light bulb, as shown. (Click the light switch to turn it to OFF.) Click the light switch to turn it to ON. What happens The light turns on Turn on Show current and select Electron flow. The moving dots represent a current of electronstiny, negatively charged particlesmoving through the wire. Voltage is a measure of how much more potential energy an electron at one end of a battery has than an electron at the other end of the battery. . How does changing the batterys voltage affect the current Changing voltage doesnt effect the current How does changing the batterys voltage affect the brightness of the light The more voltage, the brighter the light Remove the wire. What happens The current stops Activity A Ohms lawGet the Gizmo ready Click Clear. Create the circuit shown at right. (Use the 10 ohm resistor.) Click on the battery. Set the Selected battery voltage to 10 volts. Introduction Resistors are devices that slow the flow of current in a wire. The resistance of the circuit to current is measured in units called ohms.
