Why is RC coupling very popular

The RC coupling is very popular due to two basic reasons :

(I) It employs inexpensive resistors and capacitors.

(2) It provides constant voltage gain over the audio-frequency range.

RC Coupled

A Resistance Capacitance (RC) Coupled Amplifier is essentially a multi-organize enhancer circuit widely utilized in electronic circuits. Here the individual phases of the enhancer are associated together utilizing a resistor-capacitor mix because of which it bears its name as RC Coupled.

Focal points of RC Coupled Amplifier

  1. Shabby, prudent, and minimized as it utilizes just resistors and capacitors.

  2. Offers a consistent addition over a wide recurrence band.

  3. Hindrances of RC Coupled Amplifier

Unsatisfactory for low-recurrence intensification.

  1. Low voltage and power gain as the compelling burden opposition (and thus the increase) is diminished because of the way that the contribution of each stage exhibits low protection from its next stage.

  2. Dampness delicate, making them boisterous as time passes.

  3. Poor impedance coordinating as it has the yield impedance a few times bigger than the gadget at its end-terminal (for instance, a speaker on account of an open location framework).

  4. Thin transfer speed when contrasted with JFET speaker.

Uses of RC Coupled Amplifier

  1. RF Communications.

  2. Optical Fiber Communications.

  3. Open location frameworks as pre-enhancers.

  4. Controllers.

  5. Radio or TV Receivers as little sign enhancers.

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
