Power transformers are rated in Volt Ampere (VA) or kiloVolt-Amperes (kVA) or MVA rather than watts (W) because of the nature of AC power systems and how transformers handle loads of varying power factors. Here’s why: 1. Separation of Apparent Power from Real Power: In AC systems, power is made up of three components: Real … Read more
Both Nyquist plots and Bode plots are used to analyze the frequency response of a system, particularly in control theory and signal processing. They provide insights into system stability, performance, and behavior across different frequencies. However, they differ in how they present this information. We will study them one by one. Contents Bode PlotKey features … Read more
Modeling in the frequency domain is a crucial concept in control systems, signal processing, and communications. It involves transforming time-domain signals and system behaviors into their frequency components, allowing for easier analysis and design of systems, especially when dealing with oscillatory or periodic signals. Below fig is of the control system where the input, output, … Read more

Transient Response Analysis- The study of behavior (Output/Response) of a system with respect to time is called Time Response analysis. Time response is divided into two parts: Transient Response Analysis It is the response /Output before reaching the steady state or final value. The transient state is the short-term, temporary response of a system after … Read more
Resonance circuit are electrical circuits in which inductive and capacitive elements interact in such a way that their reactive effects cancel each other at a particular frequency, known as the resonant frequency. At this frequency, the circuit can exhibit special characteristics, depending on its configuration. Resonance circuits are typically classified into two types: 1. Series … Read more
There are two kinds of electrical elements Passive and active Elements. Contents Passive elements Active ElementsKey Differences in passive and active elements :Source TransformationPassive elements Passive elements are components in electrical circuits that do not generate energy but instead store or dissipate it. They cannot amplify signals or provide energy to the circuit on their … Read more
