A Volume Type Variable Resistor Potentiometer Trimmer Resistor Rheostat is the most significant component find in many electrical devices for controlling the tone, bass as well as volume. This is due to the fact that resistors can  connect together with the other components to form filters for a desired level. They can also  use in computer monitors for color or positioning as well as dimming or switching lamps. This is achieved through digital to analog and analog to digital circuits; one additional advantage is that the knob can be turned instead of typing a value every time you want to change the tint or brightness.

A Volume Type Variable Resistor Potentiometer Trimmer Resistor Rheostat is a resistor in which the electric resistance value is adjustable. A variable resistor is an electro-mechanical transducer that generally works by sliding a contact (wiper) over a resistive element. A variable resistor is use because a potential divider with 3 terminals is a potentiometer. When it has two terminals, it acts as a variable resistor, which call as a Rheostat. An electronically controlled variable resistor controls electronically instead of using a mechanical action. This resistor is call as a digital potentiometer..

An internal link is any link from one page on your website to another page on your website. Both your users and search engines use links to find content on your website. Your users use links to navigate through your site and to find the content they want to find. Search engines also use links to navigate your site. They won’t find a page if there are no links to it.
There are several types of internal links. In addition to links on your homepage, menu, post feed, etc, you can also add links within your content. We call those contextual links. Contextual links point your users to interesting and related content. Moreover, they allow search engines to find out what content on your site is related and to determine the value of that content. The more links an important page receives, the more important it will seem to search engines. Therefore, good internal links are crucial to your SEO.
