World of electronics components..

Electronics....... Have you can specifies its components in a books...! I can understand your talk. " Who is a donkey, Please look this blogger name. Cute.... He is a good example". But i like to show some simple ways to choose your components for electronics. Are you ready with me?... Just for a fun with me...Yaa.... It is always fun..
Now we can list out some components that is commonly used for all circuits.

Cute words. Only 4 letter. Really slim beauty. But it has a big role in electronics. First we need some theory about wires.
What is a wire?
A wire is conducting material with a cylindrical shape that is used to interconnect various components. Now wires has a variety of shapes and type. According to our use, we can select the correct one. First you just see some important types of wires.

Now you can get some basics about it. Yaa boss, very simple. To flow water, we use pipes. Also to flow current, we use wires in electronics.

Commonly for electronics circuits, we use single stand wires and multi stand wires. Now just try it...

Single stand wires
 What is a single?... That is a one... Nice answer. We like simple answer and simple looks. So just believe it. Single stand wire is a single conducting material with a cylindrical shape. Also it has a nice plastic coting with a attractive colour. I have a hobby to collect various colour wires due to its attraction.
Single stand wires are mostly used for connecting components in breadboard. I believe that single stand wires are not suitable for soldering. Now just test it. Use a  single stand wire and multi stand wire for soldering. Then say what you feel?....
Which is more flexible and durable?...
That is your decision.... So i leave it.

Multi stand wires
Now multi stand wires.... Multi stand wires is a collection of single stand wires in a plastic coting. 
There is no any complex theory. If you have any problem? Just go to a electronics shop and request for single stand and multi stand wires... Then return to home.... Now you can understand difference between them. Try to solder them, connect in breadboard..... Wish a nice experiments with wires.....
So last, wires are only connecting material...Forget it for future....

In almost electronics circuits, you can find resistors. So it is an important as you. 
Resistor have some basic functions. Resistor is a current limiter or voltage divider. Just leave it. We have some rules and theory's to find its value in circuit. 
All resistors have a particular colour code. Colour code is used to find out its value in ohms. We have a particular name or number to identify us.Same to that, in resistors we can find some marking in with various colours. It is known as colour code. For more reference, look the below figure. 
  Now you can identify some resistors in electronics circuits. Here is a variety of resistors are available now. So first try to understand the major types.
Now just look the below fig. 

 (a)   ¼ watt resistors, 5% precision: These resistors are available in many different resistances in the student electronics lab.  They are the most common type of resistor that you will encounter and work well for many applications.
(b)   1% precision resistors: These resistors are available in the ME Department electronics shop in W298 (ask one of the staff). 
(c)    Resistors for higher-wattage applications: Particularly in higher-current applications, you may encounter situations where a resistor will be required to dissipate more than ¼ watt.  If one of your ¼ watt resistors starts smoking, this is certainly true.
(d)   Potentiometers: These devices allow you to adjust resistances during operation of your circuit. 
Friend.....  If you feel any  problems with my stuppid theory,  just close this blog and try to enjoy a song. After a hot coffee, we can meet.

 After this small break, we want to use some resistors in various electronics circuits. So first we need some network theory in resistors. 
Now i am in my last year of engineering degree. But till, i can't clear my ideas about resistor networks. So friend, i just show some important resistor networks and evaluate it. If you have much intrested on this topic, please say to google or our wikipedia. It is always better than me.

Resistor in parellel and serial
In the above figure , we can find some simple resistor networks.
Fig a shows 3 resistor are connected in serial.  In serial connection, the tottal resistnce between node a & node b is r1+r2+r3.
Also in fig b, three resistance is connected in parellel. Here the reciprocity of tottal resistance between node a& node b is (1/r1)+(1/r2)+(1/r3).
The fig c and fig d are combinations of the series and parellel networks.
So friend, just i stop this stuppid resistance theory at here. Just go to any other good website for better information, because now i am empty.
