Filters in Electronic Instrumentation Articles: What is a Filter Circuit?: A network designed to attenuate certain frequencies but pass others without attenuation is called a filter. A filter circuit thus…
Transformers Articles: How does a Transformer Work and Purpose of Transformer: How does a Transformer Work – A Transformer Circuit is a static device comprising coils coupled through a magnetic…
Partial Discharge Measurements: Earlier the testing of insulators and other equipment was based on the insulation resistance measurements, dissipation factor measurements and breakdown tests. It was observed that the dissipation…
Transmission of Waves at Transition Points: Whenever there is an abrupt change in the parameters of a transmission line, such as an open circuit or a termination, the travelling wave…
Thevenin Equivalent Circuit: In many practical applications, it is always not necessary to analyse the complete circuit; it requires that the voltage, current, or power in only one resistance of…
Principle of Superposition Theorem: The Principle of Superposition Theorem states that in any linear network containing two or more sources, the response in any element is equal to the algebraic…
