There are how many types of electronics in the world ?

If we talk about electronics in the world, than I think that there is no limitation, because every day there new-new features updates we listening isn't ?.

Actually we can't define the limitations of electronics in the world.

But in current times, the types of electronics is,

1. Digital electronics
2. Analogue electronics
3. Microelectronics
4. Circuit design
5. Integrated circuits
6. Power electronics
7. Optoelectronics
8. Semiconductor devices
9. Embedded systems
10. Audio electronics
11. Telecommunications
12. Nanoelectronics
13. Bioelectronics

 Electronic component capacitor is very useful for checking freshness of fish !!!

Hello dear readers,

Welcome to this new concept, here in this concept you will come to know that, how we can check the freshness of fish by using capacitor ?

This information is going to be very interesting and amazing .

So let's explore this information in simple way !!!

So first of all, please guess here, how we can check the freshness of fish ? Than read this content !!!

So let's come to our topic,

In general the molecular weight of water is 81.

OR

We can say that in other words, The value of K (relative permittivity) of water is 81.

So as we know that, fish live in water.

So that, water is the important component of fish tissue skin.

So it means that, the fish is made up of dielectric material, so that it can store electric charge.

So as we know that, fish made up dielectric material, simply it's means that, water has two molecule, one is Hydrogen and Oxygen.

So that, Hydrogen contain (Positive charge) and Oxygen contain (Negative charge). Because of that, we called dielectric material.

The capacitor has two plates, so that one plates contain positive charge and another plates contain negative charge.

So these plates separated from each other by dielectric material.

So if we put or place the fish in between these two plates of capacitor.

Than, the fish tissue change the capacitance of capacitor.

So that, if the fish is fresh than it's body will be strong and having the higher value of K (relative permittivity) 81.

It means that, the value of relative permittivity or molecular weight of  higher than 81.

And if fish is older than it's body will be weak and having the lower value of K (relative permittivity) 81.

So it means here, the value of relative permittivity or molecular weight is lower than 81.

So we hope you understand this concept very clearly and simply.
