love photos

Love is like sunshine. It brings a golden glow to its beholder's face. And a warm feeling all over their body. It awakens souls and opens eyes. And when its over, it leaves billions of small memories called stars. To remind the world, that it still exists.

                                          Love is strong yet delicate

                                                         It can be broken

                               To truly love is to understand this

                                    To be in love is to respect this

Everytime you cry a tear, my heart cries along.

But you’l lnever know cause I wouldn’t tell. Everytime 

you’re hurt,

I’m hurt too. Cause that’s what love is for and I love you.

Transformer -1

principle of transformer operation........................


A transformer is a static device which consist of two or more stationary electric circuits interlinked by a common magnetic circuit for purpose of transferring electricity between them. the transfer of energy from one end to another end without change in frequency .


consider tow coil 1 and 2 simple on a magnetic circuit as shown in figure these two coil are  insulated each other and there is no electrical connection  between them let t1 and t2 be the number of turns of the coil 1 and 2. when a source of alternating voltage is applied in coil 1 and alternating current {I} gets starts flowing in it this alternating current produce a alternating flux in a magnetic circuit shown in diagram

the alternating flux links with coil 1 and induced in a alternating voltage E1 by self induction

let us make the following simplifying assumption 

(a) three are no losses  either in electrical feild or in magnetic feild

(b)the whole magnetic flux confined to the magnetic circuit so that no leakage flux 

(c) the permeability of the core is infinite

all the flux produce that also links with coil 2 and t2 turns  and induced in them a voltage E2 by mutual induction...coil 2 is connected to the load then ac current flows through itand energy will deliveed to load thus, electrical energy is transferred from coil 1 and2 by a common magnetic circuit .since there is no relative motion between the coil the frequency of the induced voltage in coil 2 is same as the frequency induced in  coil 1                                 

coil one which receives energy source from ac supply from primary coil. coil two is connected to load and deliver energy  top the load called secondary coil..
