## What is Ripple and Ripple Factor? – Formula of Ripple Factor

What is Ripple? Ripple is the fluctuating AC component present in rectified DC output. The output of a rectifier may either be DC current or voltage. In view of this, AC fluctuating component present in DC output voltage is called voltage ripple and that in...

## Average Value of AC Current – Definition, Formula and Application

Definition Average value of AC or alternating current is expressed by that DC current which transfers across any point of circuit the same charge as is transferred by the AC current for the same time. This means, if AC current I in a circuit flows...

## Root Mean Square or RMS Value of AC – Definition, Formula and Calculation

Definition Root Mean Square (RMS) value of AC current is defined as the steady or DC current which when flowing through a circuit for a given time period produces the same heat as produced by the AC current flowing through the same circuit for the...

## Difference between Concentrated and Distributed Winding

The winding used in electrical machine can be broadly classified into two types: Concentrated Winding and Distributed Winding. Concentrated Winding In concentrated type of winding, all the winding turns are wound together in series to form one multi-turn coil. Examples of concentrated winding are field...

## Armature Winding and Its Types

Definition of Armature Winding Armature winding in an electrical machine is that winding which carries the load current. In other words, it can also be defined as the winding in which emf is generated due to air gap field flux. It should be noted here...

## Difference between Lap and Wave Winding

The main difference between lap and wave winding is the manner of connecting the armature winding coil end to the commutator segment. In lap winding the top and bottom coil ends are connected to adjacent commutator segment whereas in wave winding, they are bent in...

## Advantages of Wave Winding Over Lap Winding

Wave winding posses certain advantages over lap winding. The main advantage of wave winding is requirement of lesser amount of conductor and carbon brushes. This is because the number of parallel path in wave winding is always 2, therefore two carbon brushes are only required....

## Pitch Factor or Coil Span Factor and Winding Factor

Pitch Factor or Coil Span Factor Pitch Factor or Coil Span Factor is definite as the ratio of emf generated in short pitch coil to the emf generated in full pitch coil. It is denoted by Kp and its value is always less than unity....
