Kirchhoff's Current Law ||Current Low

Kirchhoff's Current Law (KCL) is Kirchhoff's first law that arrangements with the preservation of charge entering and leaving an intersection. 

To decide the sum or size of the electrical current streaming around an electrical or electronic circuit, we have to utilize certain laws or guidelines that enable us to record these ebbs and flows as a condition. The system conditions utilized are those as indicated by Kirchhoff's laws, and as we are managing circuit streams, we will take a gander at Kirchhoff's present law, (KCL). 

Gustav Kirchhoff's Current Law is one of the essential laws utilized for circuit investigation. His present law expresses that in a parallel way the aggregate current entering a circuits intersection is precisely equivalent to the aggregate current leaving a similar intersection. This is on the grounds that it has no other place to go as no charge is lost.

As it were the arithmetical total of ALL the streams entering and leaving an intersection must be equivalent to zero as Σ I in = Σ I out. 

This thought by Kirchhoff is normally known as the Conservation of Charge, as the current is preserved around the intersection with no loss of current. Let's take a gander at a straightforward case of Kirchhoff's present law (KCL) when connected to a solitary intersection.

Feature of KCL
  • Follow low of conservation of charge
  • Applicable for any lumped circuit
  • Independent of nature of element

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 bypasses t

Negative Booster

Negative booster A negative booster is employed to conform to the regulation that the potential difference between any two points of the rail return shall not exceed 7 V. Two boosters, positive and negative, are used which are mechanically coupled together and driven by a DC motor. The positive booster is connected to the trolley wire (near the generating station) and the negative booster (separately excited) is connected to the track rail.  The 'positive booster' adds voltage to the line while the 'negative booster lowers the potential of the point it is connected to. As we go along the trolley wire away from the generating station/sub-station, the potential drop increases, and the voltage of the trolley wire falls. Since the current returns via the track rail points away from the generating station acquire high potentials. This potential is brought down by the negative boost provided by the negative booster. When the load is sufficiently far away from the generating stati
