Resistor Color Coding

In the present day scenario where most of us have digital gadgetry right in our pockets we tend to forget our basic need for understanding of "Color Coding".

Despite us being able to use the handy multi-meter it is faster and easier to just look and give the ohmic value of the Resistor. Well, here guys we'll be giving you the very famous jargon of color coding which has been in use since time immemorial.
So herez the thing just like we read from left to right, this resistor coding is also done in a similar fashion. The niche is to read it right. Since most of the tolerance band is either gold or silver in color. So keep that to your extreme right and hold it in your hand as depicted in the above figure.

Transistors And Its Practical Applications

The most widely used products in the Electronics industries is a transistor and its also the major component of any electronics equipment, so its necessary for all of us to know what basically a transistor is....and what can be its basic applications in daily life ?

When any lecturer asks you in VIVA or as a general question

"What is a transistor? And its application…."

The basic answer for this is
