Why stones and gravels are laid on the surface of High Voltage Substation?

Substations are very common in modern power systems. It may be located at the power generating station or at the middle of the transmission line or at the end. They mainly transforms voltage levels for transmission and distribution purposes. One thing you might have been noticed that almost every substation surface is covered with stones and gravels. Have you ever thought what is the reason behind doing that? Well, we will discuss one by one in this article.

How to differentiate different types of RAM?

For replacing or upgrading your desktop RAM, it’s very important to know what kind of RAM it is currently using. You can know that by reading the nameplate sticker sticked on it or looking physically. Every type of RAM operates in different voltage levels and frequency . Here inn this post we will discuss them one by one.


RAM stands for Random access memory. It helps processor to fetch data randomly as well as very fast. It stores the data temporarily for current running programs.

Like different generations of computer there are different generations of RAM. We will discuss one by one.

Easiest way to understand working of MOSFET

MOSFET¬†stands for metal oxide semiconductor field effect transistor. Like common transistors,it is also used as amplifying and switching device.The main difference from bi-polar transistor is that it’s gate (which is equivalent to base of a bipolar transistor) is electrically insulated.The metal-oxide insulation, commonly silicon di-oxide provides very high input resistance which makes the device suitable for different types of applications.

Linear Potentiometer VS Logarithmic potentiometer

Potentiometers varies potential difference between it’s terminals.It’s a very common and useful device used to vary voltage, current as well as gain in a circuit. Depending upon the physical size and form factor there are various types of Potentiometers.In this post we will differentiate potentiometers (in short POT) on the basics of Output Response with respect to angular displacement of the knob.
