Tap Changing Transformers: The excitation control method is satisfactory only for relatively short lines. However, it is not suitable for long lines as the voltage at the alternator terminals will have to be varied too…
Architecture of 80486 Microprocessor: The 80486DX is a 32-bit processor. Figure 11.46 shows the simplified block diagram of 80486 and the interÂnal architecture of 80486 Microprocessor is depicted in Fig. 11.47. The architecture of Intel's…
Frequency Response of an Op-Amp Interview Questions and Answers: 1. What is meant by frequency response? Ans. The manner in which the gain of an op-amp responds to different frequencies is known as the frequency response.…
Methods of Exciting Waveguides: In order to launch a particular mode in a Methods of Exciting Waveguides, some arrangement or combination of one of more antennas is generally used. However, it is also possible to…
Three Wire DC Distribution System: The great disadvantage of direct current for general power purposes lies in the fact that its voltage cannot readily be changed, except by the use of rotating machinery, which in…
Platinum Resistance Thermometer: Platinum Resistance Thermometer - The resistance of a conductor changes when its temperature is changed. This property is used for measurement of temperature. The Resistance Thermometer uses the change in electrical resistance…
Energy Band Diagram of Semiconductors, Insulators and Metals: Energy Band Diagram of Semiconductors, Insulators and Metals - As discussed earlier, the electrons of an isolated atom are acted upon only by the forces within that…
Step Response of an Amplifier: An alternative criterion of amplifier fidelity is the response of the amplifier to a particular input waveform. Of all possible available waveforms, the most generally useful is the step voltage.…
UJT Triggering of SCR Working Principle: UJT Triggering of SCR Working Principle - One common application of the unijunction transistor is the triggering of the other devices such as the SCR, triac etc. The basic…
Platinum Thin Film RTD Sensors: Platinum Thin Film RTD Sensors are manufactured by a very thin layer of platinum in suitable pattern to achieve smaller dimension and higher resistance, on a ceramic base. The deposition…
