Capacitor and its work

 

t is a device for string electric charge. It is a system of two (or more) plates on P; which we can store electric charge.

 

Parallel Plate Capacitor:

 

It is a simple capacitor with two parallel plates on which we store the electric charge.

 

 

Construction:

 

A parallel plate capacitor has two metallic plates with their stands and a dielectric which is air or some insulator. E.g. wax paper, wax, oil and mica.

 

Working:

 

When the plates of a capacitor are connected to a voltage source. The electrons flow from a plate A to the positive charged terminal and B plate to negative terminal. Thus plate A acquires -q charge. Due to attraction voltage on plates increases gradually. Then charging stops when the potential difference (voltage) becomes the voltage of source.

 

The modern educational system is based on giving students not only specialized knowledge, but also general knowledge, and therefore in the program you can find an uncountable number of subjects that are completely useless, and a lot of different work needs to be done for them. There is no point in studying all these disciplines, because, firstly, there will be no benefit from this, because all this will be forgotten without regular use, and secondly, there will be no time left to study what is really important and, possibly, will determine your future career.
