What is Inverter And Definition

WHAT IS NVERTERS

Inverter is a Good device Convert Direct current (Dc supply) into (Ac supply) Alternating supply.We know that A.C input voltage over D.C input voltage is called Inverter Gain.DC to Ac power conversion procedure normally work with Transistor or SCRs.This mean Convert D.C power into A.C power with SCRs Or Transistor.

There are two types of inverter base on commutation :

• Line-Commutated Inverters:
• Forced-line Commutated Inverters

Line Commutated Inverters:

When Phase controlled converter work in inverters mode it is called Line Commutated Inverters.

Forced-line Commutated Inverters:

In Forced Commutated circuit use have outside source to off device forcefully it is called Forced  inverters.

There are two types of phase inverters:

• Three Phase inverter
• Single Phase inverter

Voltage Source Inverter (VSI) or Voltage Feed Inverter:

If inverter input voltage is constant then this inverter is called  voltage source inverter (VSI) or voltage feed inverter (VFI) inverter.

CSI Or Currend Invertert Fee (CFI):

But if inverter input current is constant then this inverter is called current source inverter (CSI) or current feed inverter (CFI).

Variable D.C Linked Inverter

IF Inverter input voltage is control able then this inverter is called variable D.C linked Inverter.

USES OF INVERTERS

(Applications Of Inverters)

Inverter use in electrical and electronics Systems:
Some uses of Inverters there are:

1. Variable Speed A.C motor deives
2. Aircraft power Supplies
3. Uninterrupted Power Supplies OR (UPS)
4. HVDC Transmission
5. Induction Heating
6. Regenerative DC/AC Drives

What is digestive system

What is digestive system

Everything that we eat is changed into a liquid inside the body before we can use it.The breaking down of food into a liquid is called digestion. 
Food is digested inside a long tube inside the body.This tube is called the or the alimentary canal.The alimentary canal is over seven metres long.The walls of the gut produce chemicals called digestive enzymes in the break down food.

what is the digestion process:

Digestion of food starts in the mount.Teeth help to grind food into a pulp.At the same time it is mixed with saliva from the salivary glands.Saliva helps to soften the food.Also it starts to digest the starch in the food into sugar.The tongue helps the food to mix with the saliva and pushes it into the gullet or food pipe.To the gullet the food passes to the stomach.The muscles in the walls of the stomach squeeze and relax with gastric juice and acid made in stomach wall. Enzymes in the  gastric juice help to digestion food,when the acid helps to kill germs in the food.




From the stomach,the food passes a very less in the time,in small intestine.Here more juices mix with the food.Pancreatic juice from the pancreas contains a mixture of enzymes which continue to digest the food.

Bile from the liver breaks up oil droplets to make them easier to digest. Intestinal juice from the lining of intestine contains enzymes which complete the process of digestion.

Digested food is absorbed into the blood through the wall of the small intestine.The small intestine,which is over six metres long,has millions of tiny finger like projections called villi.A villus is about i mm long.It has a surface layer only one cell thick.it allows digested food to pass through it easily.It has a network of blood capillaries which absorb digested food and carry it to liver
  

What is Social Services

Every body has the right to live happily.There departments who help the people in their daily life to solve problem.These are social services and it is the responsibility of government to provide these services police,fire brigade and hospitals are examples of such department peoples who are very ill are take to a hospital,where they are looked after by doctors and nurses.They are given medicine to make them better.

What are social services:

There are Different services which help the police in a community the people in a  community the police,fire brigade and hospitals are the exp of social services.

what is the duty of police:

The duty of police is to keep us of any physical problems such as and property safe.
To keep us safe they have to be out on the streets to see that every one is obeying the rules,
Police who are found breaking the rules are rested by police.

Traffic Police :

Traffic police some police men direct traffic in a city.They make sure that people drive properly and obey the traffic rules.such police  men are also called traffic wardens.

Fire brigade:

Peoples who works for fire brigade are usually brave us the take risks to save others peoples lives and property.

Hospital:

People who are very ill are take to a hospital,where they are treated by doctors and nurses.They are given medicine of disease.

There are reals social services.

What is Lcd

What is Lcd

Liquid crystal display screen made of substance called liquid crystal.
The molecules of this substance line up such a way that the light behind the screen blocked or allowed to create an image.LCDs provide a shaper picture than CRTs and emit less radiation.LCD displays get input less power and take up less space than CRT.We can use lcd in two types such as computer monitor or as lCD TV because L.C.D use less power then Monitor.L.C.D is a beautiful technology then monitor.L.C.D can use on battery or UPS very easily.L.CD very less weight then CRT monitor.It is a modern technology.

What is Magnetic disk

Magnetic disk

Magnetic disk is the most widely used storage media.A magnetic disk is a thin circular metal plate/platter coated with magnetic material.Information can be recorded on or read from the magnetic surface.magnetic disk must format before magnetic disk can used.
After the formatted disk then you can store data in magnetic disk.Formatting is a process that creates tracks and sectors on the disk.Each track on a disk is divided into sectors.Any sector holds a specific number of characters.A sector is the smallest physical storage unit on a disk.Its size normally 512 bytes.
Two or more sectors combine to from a cluster .A cylinder consists of all tracks of the same number.Every cylinder contains the same number of sectors.

What is Current

What is Current ?

Current is simple meaning and daffiaction is an flow of electron charge is called current.Current unit is Ampere (A) Current show to (I)

Current are in two types:

Ac Current mean alternating current.

Dc Current mean Direct Current 

Alternating current definition :

AC current change direction and value in every second to constant speed is called ac current.

  Direct Current : 

Dc Current flow in only one direction is called direction current.

If we can current flow in electrical wire then across wire produced magnetic field.If wire change in wounded shape then wire work as a magnet. 

Wapda electrical current example of electrical alternation current.

Battery current example of direct current.

Current ( i ) = charge / time =  q / t

Current can define as ohms law

I=V/R

1 ampare =1 coulomb/sec

1 amp=1volt / 1 ohm

Alternating current have two types single phas and tree phase 

Three Phase  diagram:

Single phase have 220 volts and three phase supply have 3 phase and 1 neutral and 440 volts.

Single phase supply mostly use in homes and thee phase supply mostly use in factory or industries.
