Electric Power Single and Three Phase Power Active Reactive Apparent

Complex Power It is very conceptual and essential to understand. For establishing the expression of complex power, we have to first consider a single phase network that’s voltage and current can be represented in complex form as V.ejα and I.ejβ. Where α and β are angles that voltage vector and current vector subtend with respect … Read more

Vector Algebra | Vector Diagram

Before studying electrical engineering it is essential to know that angular relation between mainly voltage and current in a system. For understanding the relation between voltage and we should first know definition of vector and go through vector algebra and vector diagram. Definition of Vector There are some quantities which have both magnitude and as … Read more

Vector Diagram of Transformer: What it is & How To Draw

What as a Vector Diagram? A vector diagram is a diagram on which one or more vectors can be represented. On a vector diagram, alternating quantities are represented by an arrow. The length of the arrow represents the rms value of the alternating quantity. The angular position represents the relative position of a vector (alternating … Read more

Three Phase Circuit | Star and Delta System

There are two types of system available in electric circuit, single phase and three phase system. In single phase circuit, there will be only one phase, i.e the current will flow through only one wire and there will be one return path called neutral line to complete the circuit. So in single phase minimum amount … Read more
