EXPERIMENT 9: KIRCHOFF’S RULES Introduction Kirchhoff’s Law is defined through two separate components which are Kirchhoff’s Current Law and Kirchhoff’s Voltage Law. These two laws are collinearly related through its total summation being which is equal to 0, except that for Kirchhoff’s Current Law having its variables to be of currents flowing into and outward a node (fig.1), and for Kirchhoff’s Voltage Law having its variables in terms of the drops and rises of its voltages in a closed loop (fig

switch, and an assortment of known resistors along with one unknown resistor. We measured the current and voltage of the entire circuit as well as the potential drops across each resistor to determine the parameters of the circuit including the resistance, voltage, and current for each component. For this experiment we utilized varying forms of Ohm’s law (V=IR), rules for resistors in series (Rtotal=R1+R2+…) and parallels (1/Rt=1/R1+1/R2+⋯), and Kirchhoff’s Junction Rule (ΣIi=0). For these models

The Uncertainty principle In 1927, Werner Heisenberg was working at Bohr’s research institute in Copenhagen, Denmark. Neil Bohr and Heisenberg were working closely together on theoretical investigations of quantum theory and nature of physics. Heisenberg was left back at the centre alone when Bohr was away skiing. At this point, Heisenberg realized the limits of physics and physical reality. He realized that it in the act of observing, the observer somehow, manages to alter the reality. This observation

¬¬¬¬¬¬Abstract Electrical circuits are described with mathematical expressions. Usually, it is possible to calculate the currents and voltages in a circuit by solving a set of equations, the calculations are required to design a safe circuit.and this is one reason why advanced mathematics is so important in the field of electrical engineering. The circuit equations can be determined using Ohm’s Law, which gives the relationship between voltage and current in a resistor (V=IR), and Kirchhoff’s Current

This chapter focuses on AISI A2 material, its properties and composition. A brief explanation is provided about wire electrical discharge machining (WEDM) process, its process parameters and its various advantages and disadvantages. The knowledge of these will be beneficial in understanding the different effects of the process parameters of the WEDM on the response parameters. 1.5 NON-TRADITIONAL MACHINING In Conventional machining or traditional machining the tool required is harder than the work

The International Brotherhood of Electrical Workers (IBEW) is a great opportunity for anyone who wants to become a future journeyman electrician, they must be willing to work hard and have in interest in the construction field. The IBEW apprenticeship programs are designed to have students go to school and work at the same time. This allows students to make a living, complete the education requirements needed to become a licensed electrician and have learned valuable job experience. There are a number

INTRODUCTION 1. INTRODUCTION 1.1 Fundamentals of capacitor Capacitor is very useful component in the field of engineering and it is used in various electrical and electronic circuitries. Capacitor stores energy in the form of electric field. Capacitor also known as condensers which stores energy when charge and release energy when discharge . There are different forms of capacitors which are used widely, but common thing about this all capacitors is that they are made of two conductors

103 The war of the currents was a concept created by Tesla, Thomas Edison and Westinghouse so as to determine between direct current and alternating current which would be standard. Edison championed the direct-current system, in which electrical current flows steadily in one direction, while Tesla and Westinghouse promoted the alternating-current system, in which the current’s flow constantly alternates. He had many patents on various things including the phonograph, motion picture camera

flashlight bulb, which will produce light. That limitation of electrons can also be called resistance. Copper wires are commonly used as a form of bridge for circuits (The Energy, 2012). Atoms can slow down and even reverse the direction of electrons by colliding with them. During the collision, the electrons transfer and lose energy to the atoms. "This energy appears as heat, and the scattering is a resistance to the current" (The Energy, 2012). A good example to give students about how the current

duplicate the results that Heinrich Hertz had claimed to achieve in affirming the existence of electromagnetic waves, the discovery of which Hertz announced in 1887. While replicating Hertz’s experiments, Tesla experimented with violently abrupt DC electrical discharges and discovered a new force in the process. Only after conducting exhaustive experimental trials

3. Insulation material: made from XLPE and isolate between the three phases, its thickness is about 5.5 mm along the cable 4. Outer semiconductor: uniformly distribute the voltage on the surface of the insulation 5. Earth layer: made from copper, used to ground the cable, in case of short circuit it protect the cable by leaking the short circuit current into the ground, its thickness is about 25mm2 area 6. Filling: synthetic fibers used to make the cable circular and to fill the gap between the phases

My intended major is computer science and engineering. When I was very young, I always wanted to have a computer in order to play computer games. Once I owned a computer I realized that there are a lot of things you can do with computers besides gaming. This influenced me to want to get a job working with computers. I come from China, due to the Chinese educational background, all the knowledge was passed from the teacher to student, it turned out that I memorize a lot of theory, but I do not know

There are many types of energy production that are currently being utilized nowadays. In a sense, humans can also produce their own energy by the use of sound. But nowadays, energy has been used in the form of electricity. In which many types of electricity production take places such as hydroelectric power plants, geothermal power plants, oil power plants, and the windmills by the use of wind energy. Wind energy is the energy produced by the wind turbines inside a windmill. It is mounted on a tower

electricity as well as other methods of the transmission of electricity. His more famed rivalry, Thomas Alva Edison, was an American inventor who invented many famous inventions also based on the use of electricity, the transmission of electricity, and electrical devices. Both inventors of the ninetieth and twentieth century redefined and expanded the uses and the understanding of electricity. Both of Tesla’s and Edison’s inventions are very important to acknowledge because without them, we would not be

Dennis Nedry and John Hammond wanted to get rich, while Sal wanted to see her mother; however all wanted to complete their mission no matter what it takes. Dennis Nedry was experienced with the computer, and was one of the computer programmers for Jurassic Park. A reader must know this to understand what role he played in Jurassic Park. The book states, “Nedry had mumbled about doing computers on the island.” (Crichton) Nedry was what someone would call a ´double agent´. He worked for both InGen

Did you know that Leonardo Da Vinci discovered density 400 years before scientists could explain it? Did you also know that Thomas Edison discovered “etheric force” which led to the invention of the radio? Although both of these men were geniuses in their own time, they are still remembered because of their impact on the world today. Leonardo Da Vinci, known as a great painter, also had a knack for inventing. “At age 30, he first explored his engineering talents and went to work as a military
