Semiconductor :
We have studied about Insulator and conductor. These two concepts we know that.
Lets know simply what is Insulator ?
Insulator : Insulator work as, it not allow to conduct the electricity as well as heat, so that's why we called this is a bad conductor.
This is possible to conduct electricity in Insulator how ? the answer is "Yes". Because, If any Insulator material sustain heat constantly, than it is very easily electricity pass through it.
But on the earth there is not "Yet" material to founded, who sustain heat constantly without any damages.
Let's take an Example 1: If we want to pass electricity in plastic straw pipe, than it is possible to pass electricity in it, But one condition in that is, only and only it's able to sustain heat constantly.
And that's why, the Insulator properties matter doesn't able to conduct heat and electricity.
Conductor :
What is conductor ?
Conductor is a very good conductor of heat and electricity. Conductor can allow to Conduct electricity in Bi-directional in Alternate Current/voltage like Sinusoidal wave of current or voltage.
what issue we face Because of Bi-directional flow, All we know that, in our home, the current come in form of AC (Alternate Current), So because of that, the current in sinusoidal wave form so that's why it constantly fluctuating up and down. But we know that, in our electronic device or electronic circuit only and only work on DC current. So providing AC TO DC here Semi-conductor Concept is important to know.
So overcome this issue conducting electricity in Bi-directional flow there is one solution for this is Semi-Conductor.
Semi-conductor : Semi-conductor is a conductor which means, it allow electricity to flow as well as it acts as resistor also, because semi-conductor only allow to flow in one direction so that's why we called this is a Uni-directional conductor.
In some condition Semi-conductor act like Conductor and in some condition semi-conductor acts like Insulator.
Lets take an Example to understand this :
Here, as you can see that , here we take half wave rectifier. If At point (A) consider there is Positive volt and At point (B) there is Negative volt, than only our circuit conduct in Semi-conductor, Because here diode only work in forward direction mode and not conduct in reversed direction mode. In forward direction mode Semi-conductor work as conductor and in reversed direction mode Semi-conductor work as Insulator.
So basically, here in this circuit one Semi-conductor we use as a Diode, So all the major role play by this small diode and this diode come in Semi-conductor family.

Relay is a component used as switches in 18's and 19's century.
Relay was invented in 1835 by the brilliant US scientist Joseph Henry (1797–1878).
Hello friends welcome to this french toast recipe here you know the whole process of making french toast at home.
Now first we discuss all the ingredient we take to making french toast
Ingredient :- Bread slice - 3, Egg - 2, Salt-1/3 tbsp, Milk - 2-3 tbsp, Butter and Honey - 2tbsp (optional)
Step 1: Now first we take egg in bowl and crack the egg in a bowl.
Step 2: Add 2 -3 tbsp milk in egg bowl
Step 3: Add 2 - 3 tbsp milk in eggs bowl
Step 4: whisk it well with spoon.
Step 5: In this step turn on the flame and heat a pan & add some butter.
Step 6: Dip the bread slice into the egg batter and place it on pan.
Step 7: Cook it on medium flame for few seconds.we flip bread slice as egg set in bread and back side also we cook it for few second.
Step 8: Once it turns light golden, then take it out from the pan.

Actually
what happened behind this day is, we all are very familiar with the western
countries culture. Every western couple, they are not believe in marry. They
always believe in “live in relationship”.
The meaning
of “live in relationship” is ,for a some time or for some days, they live like a husband & wife with each other. And meaning of “Marry” word is totally opposite
from “live in relationship” Marry means for lifetime couples live with each
other.
In the land of Rome, the great saint valentine born. When saint valentine seen, the culture
of western and culture of Easten countries. They totally surprised, and
think how vast difference in between both Easten & Western culture.
They seen
that in eastern country side, couples marry with each other and live for
lifetime each other. But in case of western country side couples not marry, they
only believe to “live in relationship”.
To stop this
tradition “live in relationship” they put their voice agaist this culture. And
start motivate couples to marry with each other. But by seen all this incident
happend in his country.
The Rome king Claudius believe in, female is only for brothels. But in the state of Rome, this
saint valentine go to every people house and tell to them, Please marry with
each other and live for Lifetime.
The reason
behind, why great saint valentine teach people to marry with each other.
i》In married life, the complexity is reduces.
ii》There are very less chance of getting bigger disease.
iii》Getting of veneral disease is less.
Saint
valentine are very popular and famous for his marry culture in the Rome. By
seen all this “marry culture” in Rome. The King Claudius are very Angry against
saint valetine and give order to hang.
In those
day’s whatever order given by the King, that is used to the law. On 14 February since 4058, the great saint valentine hanged.
So that ,the
people or couples who inspire by this saint valantine and get marry. They are
very sad. So in the remembrance of the great saint valentine, so this day celebrate
as “valentine's day”.
But we celebrate this day because we know this day is a romance day for Girlfriend & Boyfriend.
And we see in our society, this valentine day celebrate in our school, colleges even our houses. But in our country, our girls and boys send valentine cards each other and what they write in the card ! that is “would you make my valentine this year”.
But we Don’t know actually why we celebrate this valentine day. For what
reason we celebrate, the answer is, without any reason. We celebrate is because, we think this day is specially for girls, boys and couples romance. But this is not the truth behind, on this day we all tribute to the great saint Valentine.
Salute to Saint Valentine who came to earth and showed us the right path.
I hope this year you know very clearly, that is why we celebrate valentine’s day every year.
Likethis!
1) In Microwave inner side there is strong metalbox, and there is a microwave generator called a magnetron. When you start cooking, the magnetron takes electricity from the power outlet and converts it into high-powered, 12cm(4.7inch) radiowaves.
2) The magnetron blasts these waves into the food compartment through a channel called a waveguide.
3) The foods it on naturntable, spinning slowly round, so the microwaves cook it evenly.
4) The microwaves bounce back and forth off the reflective metal walls of the food compartment, just like light bounces off a mirror. When the microwaves reach the food it self they don't simply bounce off Just as radiowaves can pass straight through the walls of your house, so microwaves penetrate inside the food. As they travel through it, they make the molecules inside it vibrate more fastly.
5) Vibrating molecules have heat so, the faster the molecules vibrate, the hotter the food becomes. Thus the microwaves pass their energy into the molecules in the food, rapidly heating it up.
I hope you understand these concept in simply and easily.
If you have any doubt or queries regarding to this concept, ask frequently we will happy to reply.

Hello my friends welcome to this blog post. Today we know some step to identify between fake and real battery of phone/mobile. As you know that in the name of company brand name, many fraud people sell battery, which is completely duplicate or you can say local product.
Here I explain some basic step to recognize between
fake & real battery of phone/mobile.
Step 1 Smell
battery from nose :- In your hand when you smell local/Fake battery, you found
some smell of (Lithium ion). But in case of Real/Original battery you will not
found any type of (Lithium-ion) smell.
You might think here, why fake battery smell
(lithium-ion) & in real battery we not found any smell of (Lithium-ion) ???
Because in fake battery there is not any insulation
covered, that’s why from battery constantly (Lithium-ion) gas releases and that's why, we able to smell easily. But in Real/Original battery there is insulation is provided to protect battery (Lithium
lion) that’s why we not able to smell.
Step 2 In
fake battery there is no barcode :- Whenever you go to buy mobile battery, you
should check the battery backside there is barcode or not. If you found barcode backside then it's mean, it is Real/Original battery. But when you not found barcode backside of battery then it's 100% fake or duplicate battery.
Steps 3 Check weight of your real battery & fake battery whatever mobile shopkeeper give you :-
If your mobile battery is damage, so you should take
your damage real battery from your phone & go to mobile shop.
Shopkeeper gives you some brand battery of your phone, so
what you have to do first is after checking above all two steps this third last steps is very accurate & correctly differentiate between real and fake
battery.
What you have to do is, in your one hand put your
damage real battery & another hand put whatever battery given by shopkeeper.
And now check it's weight.
You find that real battery weight is greater than fake
battery.
So that You can easily differentiate between real
& fake battery.
