BOEING COMPANY(EVERY ELECTRICAL ENGINEER MUST KNOW ABOUT IT)

It is one of multinational companies.It manufacturers airplanes and many other military equipments like missiles etc.,
It was sarted by WILLIAM E BOEING.He studied at YALE UNIVERSITY. He worked initally in a timber industry and he became wealthy and known about wooden structures.Slowly he built a seaplane and built ships. And it satarted to manufacture different types of planes which are used for wars.

Weight affect growth rate

Hai friends,
Please give one minute of your precious time and read this article.
Do you know one of cause for decrease in growth rate(the rate at which our height increases) in present generations is carrying weights.Many of the servays says that weight lifting affects the growth rate.Weight lifting decreases the growth rate or stops the growth. We may think that we are not carrying any weights it is obsoletely wrong but we have carried and even now every child is carrying a lot of weight daily .I mean from our nursery to 🔟 th class we have many books 📚 to carry.Every day we used to carry a lot of books 📚 from home 🏡 to school and from school to home.(CHILDHOOD IS THE MAJOR PART WHERE WE GROW MORE HEIGHT )

As I have already said that carrying weights decreases the growth rate.
So i want to make you aware about this and say to children 🚸 not carry books 📚 daily from home 🏡 to school 🏫 and from school 🏫 to home 🏡 instead they may keep their books in school.

I am not saying that if we doesn't carry books 📚 we will become height,but I am  saying about a factor which affects our height.
You can take a live example:
Our parents and grandparents have also studied to some extent.Many of us are lesser in height compared to them it is because in their childhood they have very less books 📚.

Share this if you agree.

Dual networks

Two ✌ circuits are said to be duals of each other if cut set matrix of one circuit equal to the tieset matrix the later

Advantages of employing THREE phase circuits

1. For a given size of machine 3 phase machines provides more Output compared to that of single phase machines.
2.The amount of copper required to transfer power is less in three phase circuit when compared to that of single circuit
3.Transmission of power using three phase has more efficiency compared to that of single phase
4.Three phase has good voltage regulation compared to single phase
5.For a given size of rating three phase machines are smaller in size compared to that of single phase
6.Three phase circuits can produce rotating magnetic field where as single phase cannot
7.Three phase motors are self starting,where as single phase motors are not self starting
8.Three phase motors have less pulses where as single phase motors have more pulses,So the torque produced by three phase is uniform torque and the torque produced by single phase is uniform torque
9.The equipment of three phase has less losses when compared to that of single phase
10.If Six or twelve phase supply is provided to the rectifier then the output has less ripples

FLEMINGS LEFT HAND RULE

Flemings right hand rule is used to identify the direction of induced current when a conductor cuts the magnetic field

Stretch the THUMB,FIRST FINGER,MIDDLE FINGER OF YOUR RIGHT HAND MUTUALLY PERPENDICULAR
IF THUMB SHOWS THE DIRECTION OF FORCE AND
FIRST FINGER REPRESENTS THE DIRECTION OF MAGNETIC FIELD
THEN MIDDLE FINGER REPRESENTS THE DIRECTION OF CURRENT

Note that Flemings right hand rule is used only for generator
But not for motor

Easy ways to remember:

1.  [Flemings right hand rule]=[generator]
Both the words have two R's it is one way of remembering that Flemings right hand is used for generator

2.  FBI
F(force)-THUMB
B(magnetic field)-FIRST FINGER
I(current)- middle finger

CAN ELECTRICITY PASS THROUGH PENCIL LED

Yes,because pencil led is made of GRAPHITE which is a conductor of electricity
