EMF Equation of a transformer
The emf equation of a transformer is derived by considering a single-phase transformer. When a single-phase AC supply is given to a transformer, the emf gets induced in the secondary…
Definitions of Electrical Engineering
Electrical engineering is built up of number of basic definitions and concepts. Without understanding these terms, you can’t be able to learn electrical engineering. So, here I am sharing some…
Construction and working Principle of Transformer
The transformer is a static device in its construction and the principle behind the working of transformer is Faraday’s law of Electromagnetic Induction. In this article, let us learn about the…
Voltage regulation of Alternator by MMF method
Voltage regulation of alternator by MMF method requires mmf (which is a product of field current(I) and number of turns(N) of field winding) for two separate purposes. It must have…
Voltage regulation of Alternator by EMF method
The voltage regulation of alternator by EMF method involves the EMF quantities of all the armature parameters (armature resistance, Armature leakage reactance, armature reaction). The drop due to armature reaction…
Voltage Regulation of Alternator
The voltage regulation of an alternator is defined as “the rise in voltage at the terminals, when the load is reduced from full load rated value to zero, speed and field…
Construction and working of alternator
The Construction of alternator or synchronous generator is very much similar to the DC machines. In the DC generator, the armature winding is placed in the rotor and the field…
Laws of Electrical Engineering
Basic Laws of electrical engineering are stated by great inventors, who have derived the laws from their scientific innovations. They have proved the nature and behavior of electricity with their…
