Sinusoidal Voltage Equation

A sinusoidal voltage can be described by the equation: v(t) = VM sin (ωt + Φ) or v(t) = VM cos (ωt + Φ) where v(t) Instantaneous value of the voltage, in volts (V). VM Maximum or peak value of the voltage, in volts (V) T Period: The time taken for one cycle, in seconds… Read More: Sinusoidal Voltage Equation »

Explanation of Hysteresis Loss & Eddy Current Losses in Transformers

Transformer is very simple and basic part of electrical system and considered most efficient of electrical components of machines. If we consider experimental models which are using superconducting windings then we may talk about achieving the the performance of 99.75 percent as well. In practice, energy is found to be lost in the windings, core and… Read More: Explanation of Hysteresis Loss & Eddy Current Losses in Transformers »

All About Magnetism Magnetic Field and Magnetic Force

What is Magnetism? Magnetism is the study of magnetic fields and their effect on materials. The effect is due to unbalanced spin of electrons in atom. It is readily observed every day from the simple magnet that attracts nails and other metals to cassette tapes to magnet-driven trains. In terms of applications, magnetism is one of… Read More: All About Magnetism Magnetic Field and Magnetic Force »

Electromagnetic Induction | Faraday Law & Lenz’s Law Explained

To best understand the Electromagnetic Induction lets first have a look on two important laws relating to the subject of this article. Lenz’s law is named after a Russian physicist of Baltic German descent Heinrich Lenz in 1834, and it states that, if an induced current flows, its direction is always such that it will… Read More: Electromagnetic Induction | Faraday Law & Lenz’s Law Explained »

Balun Transformer – Balanced vs Unbalanced Transmission Lines

What is a balun? A Balun is special type of transformer that performs two functions i.e. impedance transformation and balanced to unbalanced transformation. The term balun is a contraction of “balanced to unbalanced transformer” Why do we need a balun? Baluns are important because many types of antennas (dipoles, yagis, loops) are balanced loads, which… Read More: Balun Transformer – Balanced vs Unbalanced Transmission Lines »
