We introduce you 3 new theories for advance electrical circuits, superposition theorem, Thevenin’s theorem and Norton’s theorem. The superposition theorem that applies in electrical circuits states that for a linear system the voltage and current in any branches of a bilateral linear circuit having more than one independent source equals the algebraic sum of the response caused by every independent source acting alone, where all the independent sources are replaced by their internal impedances. Superposition Theorem evaluating the segregated currents to combine together, replacing all others voltage sources by short circuit and all other current sources by the open circuits. To verify the contribution of each individual source, all of the sources …show more content…
Power dissipations do not algebraically add to an accurate total when there is only one source is take into account at a time. The needs for linearity also mean this Theorem cannot be applied in circuits where the resistance of a component changes with current or voltage. Other than this, another prerequisite for Superposition Theorem is which all of the components must be bilateral, which means that they act the same with electrons flowing in any direction through them. Resistors do not have polarity-specific behavior and the circuits must all meet this criterion. Thevenin’s Theory is a circuit which contains any combination of batteries and resistance with two terminals can be replaced by a single series resistor and a single voltage source. The value of the voltage is the open circuit voltage at the terminals and the value of resistor is the voltage source divided by the current with the terminals of the short circuit. In a circuit theory terms, the theorem allows any one-port network to …show more content…
In Norton theorem the circuit are replaced and connected to a particular branch by equivalent current source. In this theorem, the circuit network is reduced into a single constant current source in which the equivalent internal resistance is connected in parallel with it. Every voltage source can be changed into an equivalent current source. Norton’s Theorem declares that it is possible to simplify any linear circuit no matter how complex it is, to an equivalent circuit with just a single current source and parallel resistance connected to a load. The quialification of linear is unanimous to that which we found in Superposition Theorem, where all underlying equations must be linear. Supposing in a complex network we have to find out the current through a particular branch. If the network has one of more active sources, then it will automatically supply the current though the branch. As the current comes form the network, it can be considered that the network itself is a current source. In the Norton theorem, the network with dissimilar active sources is declined into single current source. The internal resistance is nothing but the looking back resistance connected in parallel to the derived source. The looking back resistance we said is the equivalent electrical resistance of the network when someone looks back into the network from the terminals where said branch is connected. While calculating the equivalent
Experiment 7 In this experiment we configured several DC circuits consisting of an emf and a network of resistors. The circuits were composed of a power supply, two DMMs, a circuit board, an SPST 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.
Existing basic unit is shown in fig.2.1. As shown in fig.2.1, the basic unit consist of three dc voltage sources and five unidirectional power switches. In this structure, power switches (S_2,S_4),(S_1,S_3, S_4, S_5), and (S_1,S_2,S_3, S_5) should not be simultaneously turned on in order to protect the dc voltage sources from the short circuit. Table 2.1 shows the existing basic unit power switches turn on and off states, where the basic unit is able to generate three different voltage levels at the output that is 0, V_1+V_3, and V_1+V_2+V_3. It is important to note that the basic unit is only able to generate positive levels at the output.
4.4.4. Vulnerabilities Weaknesses, insecure network, defects, in any SCADA system that can be increase the access of unauthorized advantages. A single defect allow an attacker to gain information that defect is define as vulnerability. 4.4.5. Damage potential
In the Opinion Announcement of Morse v. Frederick, Justice Roberts said, "...students do not shed their First Amendments rights at the schoolhouse gate... The rights of students at {a} school are not the same as the rights of adults in the community at large" (Morse). The point he is getting across is that even though students still have their first amendment right at school it is more filtered as they are required to follow school policy (Morse). In the case of Morse v Frederick, his first amendment was not broken as he was promoting illegal drug use at a school event which is explicitly prohibited at school no matter if at school grounds or not (Morse). From this case, it is further understood that students still have some right to be free
Gerrymandering is drawing political boundaries so that your political party has a numerical advantage over the other party.1 An illustrative example of how to win a district through gerrymandering from a Washington Post article is on the right. Gerrymandering could concentrate opposing votes into a few districts to gain more seats for a majority in certain districts. Gerrymandering can also be used to help or hinder a certain demographic, like a political, racial, linguistic, religious or class group. For example, two terms used in gerrymandering are “packing” and “cracking”.
The butterfly effect is an idea where a small disturbance at one point in the system results in a large deviation at later points. Its name comes from an analogy used where if a butterfly flaps its wings in Mexico, then future weather patterns will be drastically different compared to what they would be because of the small amount of random chaos given to the wind by the butterfly. This is taken for granted by philosophers, calculated by mathematicians and forgotten by the general public. This ignorance is exactly what Nick Carraway abhors in the novel The Great Gatsby. Carelessness is a bad trait when it comes to other peoples lives, but it carries with it a general sense of not worrying about the future.
The states b, e, and f can also be merged into one row. Finally c and d can be replaced by a, e and f can be replaced by b. New reduced table and final reduced table are shown below. Step 3. In order to obtain the circuit described by the reduced flow table, it is necessary to assign to each state a distinct binary value. This assignment converts the flow table into a transition table.
Additionally, power is anonymous without main body. Everyone is a point in the power relationship; they can be both executor and monitored
The first two letters in the acronym i.e., S (strengths) and W (weaknesses) are referred to as internal factors, which means the resources and experiences that are available to the organization. Examples of areas generally considered
Robert Ross’s journey throughout the novel leaves him unable to recognize his reflection, expecting to see the image of a god, he sees the image of a scarecrow. Findley writes, “He’d thought he would stand and see himself like a god in the glass—and there he was: a scarecrow” (Findley169). Findley portrays Robert’s moment of blindness as a connection to the changes he undergoes throughout the novel. Robert at this point in unable to recognize himself as the young boy he started off as or the hero he wanted to become. Instead, the war strips his character and left him feeling as if he has no connection to who he used to be, truthfully, he isn’t and in this scene Robert understands this.
I could also use one super power to fill another superpower. For example, a villain has trapped me in a vacuum. If I want to get out of there and use fire to do so, I couldn 't because there would be no air. So, I would first fill up the room with air (like a plant) and then use it to blow up the vacuum with fire (light a match) and use
looking and seeing is different. Looking is simply physical vision. In contrast, seeing is being engaged on a deeper level. The narrator shows that he is capable of looking; looking at his wife, Robert, and his house. The narrator is not blind therefore feel superior.
1) Expectancy violations theory is communication theory in which the one communicator violates the interpersonal expectations of another communicator. The violation can either be positive or negative. A positive violation increases the attractiveness and credibility of the communicator who is doing the violation. Whereas a negative violation causes the communicator to want to respond or behave in a more socially accepted manner. In the scene that Rachel and Dev pay Grandma Carol a visit, Dev tells Grandma Carol that he expected her to be racist.
Fallacy • Fallacies are defects in an argument. • Fallacies cause an argument to be invalid, unsound, or weak. Formal Fallacies • Identified through discrepancies in syllogistic patterns and terms. • Only found in deductive arguments.
Smart grid communication architecture is typically comprised of three interconnected networks: Wide Area Network (WAN), Neighborhood Area Network (NAN), and Home Area Network (HAN) .HAN collects the data from the home appliances. NAN transmits the data from HANs and other collectors to WAN. WAN forwards the data from NANs to the data
