Wind Energy and Wind Power Plant: Wind is a form of solar energy. It is caused by the uneven heating of the atmosphere by the sun due to the irregularities of the earth's surface, and…
Wien Bridge Oscillator using Op Amp: This is also called RC oscillator which uses RC type of feedback network. The main difference between phase shift and Wien bridge oscillator is that the R-C phase shift…
Wien Bridge Circuit Diagram: The Wien Bridge Circuit Diagram shown in Fig. 11.27 has a series RC combination in one arm and a parallel combination in the adjoining arm. Wien's bridge in its basic form,…
Wideband Antenna Types: It is often desirable to have an antenna capable of operating over a wide frequency range. This may occur because a number of widely spaced channels are used, as in short-wave transmission…
Why we need for Power System Protection? Need for power system protection are growing fast with more generators, transformers and large network in the systems. For system operation a high degree of reliability is required.…
Wheatstone Bridge Diagram: A Wheatstone Bridge diagram in its simplest form consists of a network of four resistance arms forming a closed circuit, with a dc source of current applied to two opposite junctions and…
What is Welding Process? - Definition, Classification, Advantages and Disadvantages: Welding Process is a materials joining that produces coalescence of materials by heating them to the welding temperature with or without the application of pressure…
What is Waveshaping? - Types Waveshaping is a part of signal processing where the signal waveform has to be properly shaped before amplification. It may be defined as a process of generating new waveforms from…
What is Wave Particle Duality? Since waves exhibit particle-like behavior, then the particles also should exhibit wave—like properties. This theory (de Broglie) is based on the existence of a wave particle duality principle. The momentum…
What is Wave Analyzer?: It can be shown mathematically that any complex waveform is made up of a fundamental and its harmonics. It is often desired to measure the amplitude of each harmonic or fundamental…
