Superposition Theorem

Superposition Theorem 

Superposition Theorem


The superposition theorem depends on the idea of linearity between the reaction and excitation of an electrical circuit. It expresses that the reaction in a specific branch of a direct circuit when different free sources are acting in the meantime is equal to the entirety of the reactions because of every autonomous source acting at once. 

In this strategy, we will consider just a single autonomous source at any given moment. In this way, we need to wipe out the staying free sources from the circuit. We can take out the voltage sources by shorting their two terminals and also, the present sources by opening their two terminals. 

Thusly, we have to discover the reaction in a specific branch 'n' times if there are 'n' free sources. The reaction in a specific branch could be either present coursing through that branch or voltage over that branch. 

The strategy of the Superposition Theorem 

Take after these means with a specific end goal to discover the reaction in a specific branch utilizing the superposition theorem. 

Stage 1 − Find the reaction in a specific branch by thinking of one as the free source and dispensing with the staying autonomous sources introduced in the system. 

Stage 2 − Repeat Step 1 for every single free source shown in the system. 

Stage 3 − Add every one of the reactions keeping in mind the end goal to get the general reaction in a specific branch when every single autonomous source is available in the system.

    Limitations of Terzaghi Theory

    Limitations of Terzaghi Theory The value of the coefficient of consolidation has been assumed to be constant.  The distance d of the drainage path cannot be measured accurately in the field. The thickness of the deposit is generally variable, and an average value has to be estimated.  There is sometimes difficulty 1n locating the drainage face, sometimes thin previous seams that can act as good drainage face are missed in the boring operations. The equation is based on the assumption that the consolidation is one-dimensional. In the field, the consolidation is generally 3-dimensional. The lateral drainage may have a significant effect on the time rate of consolidation. The initial consolidation and secondary consolidation have been neglected. Sometimes these form an important part of the total consolidation. In actual practice, the pressure distribution may be far from linear or uniform. Read More Muller-Breslau principle

    Price Guard Wire Method

    Price Guard Wire Method Some form of  Price Guard Wire Method  is generally used to eliminate the errors caused by leakage currents over insulation. Fig. 3.14 illustrates the operation of This Method. In fig 3.14(a), a high resistance mounted on a piece of insulating material is measured by the ammeter voltmeter method. The micro-ammeter measures the sum of the current through the resistor (IR) and the current through the leakage path around the resistor. The measured value of resistance computed from the readings indicated on the voltmeter and the microammeter, will not be a true value but will be in error.   Figure 3.14 Application of  guard  circuit for measurement of high resistance In fig, 3.14 (b), the  guard  terminal has been added to the resistance terminal block. The  guard  terminal surrounds the resistance terminal entirely and is connected to the battery side of the micro-ammeter. The leakage current IL now

    Streamer Theory of Breakdown in Gases

    Streamer Theory of Breakdown in Gases According to the Townsend theory firstly, current growth occurs as a result of the ionization process only. But in practice, breakdown voltages were found to depend on the gas pressure and the geometry of the gap. Second chances time lags of the order of 10-5 s, but practically it was observed to occur at a very short time of 10-8 s. Also, the Townsend mechanism predicts a very diffused form of discharge, that actually discharges were found to be filamentary and irregular. Townsend's mechanism failed to explain all these observed phenomena and as a result, The Streamer theory was proposed. The theory predicts the development of a spark discharge directly from a single avalanche in which the space charge developed by the avalanche itself is said to transform the avalanche into a plasma steamer. In Fig 1.7, a single electron starting at the cathode by ionization builds up an avalanche that crosses the gap. The electrons in the a
