Almost 80% of coal and 90% of oil that India consumes is imported.India looses a huge amount of foreign currency each year. It’s not a good thing for any country. Today we are very much dependent upon fossils fuels like coal and mineral oil. The storage of these sources are declining every day. Oil is […]
Power generation is almost instantaneous. In conventional systems at a instant of time power generated = power consumed. Now a days non-conventional energy sources like solar and wind energy is getting connected with grid. Most of the non-conventional sources are time specific and unreliable in nature. Thus we need a good power storage solution to improve reliability and integrity of the power system. Batteries have been used for many years to store energy. But they are expensive and unsafe. In last decade many scientists ,entrepreneur has come up with different energy storage solutions. Here is the 5 brilliant methods to store solar energy without conventional batteries.
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.

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.
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.
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.
PGA (pin grid array) is one type of processor packaging which offers more pins than DIP( dual inline package ). It’s a square or rectangular shape package. Pins are arranged in a matrix like manner at the bottom side of the processor. Pins are generally spaced 2.54 mm (0.1″) apart, and may or may not cover the entire underside of the package.
When you don’t have data sheet of any transistor in your hand, you face trouble in determining legs of transistors. Here I will tell you, How to determine legs of a transistor using a multimeter.
