Fleming Left-Hand Rule

It is discovered that at whatever point a current conveying conductor is set inside an attractive field, a power follows up on the conductor, toward a path opposite to both the headings of the current and the attractive field. 

In the figure, it is demonstrated that a segment of a conductor of length L set vertically in a uniform flat attractive field quality H, delivered by two attractive shafts N and S. In the event that I am the present coursing through this conductor, the size of the power follows up on the conductor is, 

Hold out your left hand with the index finger, second finger and thumb at right edge to each other. On the off chance that the forefinger speaks to the bearing of the field and the second finger that of the present, at that point thumb gives the heading of the power. 

While, current courses through a conductor, one attractive field is actuated around it. This can be envisioned by thinking about quantities of shut attractive lines of power around the conductor. The heading of attractive lines of power can be controlled by Maxwell's corkscrew rule or right-hand grasp rule. According to these rules, the course of the attractive lines of power (or transition lines) is clockwise if the current is streaming far from the watcher, that is if the bearing of current through the conductor is internal from the reference plane as appeared in the figure. 

Presently if an even attractive field is connected remotely to the conductor, these two attractive fields i.e. field around the conductor because of current through it and the remotely connected field will communicate with each other. We see in the photo, that the attractive lines of the power of outside attractive field are from N to S post that is from left to right. The attractive lines of the power of outside attractive field and attractive lines of power because of current in the conductor are same way over the conductor, and they are inverse way underneath the conductor. Henceforth there will be bigger quantities of co-directional attractive lines of power over the conductor than that of underneath the conductor. Thus, there will be a bigger convergence of attractive lines of power in a little space over the conductor. As attractive lines of power are never again straight lines, they are under strain like extended elastic groups. Thus, there will be a power which will tend to move the conductor from more thought attractive field to less focused attractive field, that is from show position to downwards. Presently on the off chance that you watch the bearing of current, drive and attractive field in the above clarification, you will find that the headings are as indicated by the Fleming left-hand rule.

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
