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.
In summer season 15% percent of domestic electricity is consumed by refrigerators.As it adversely affects to your pocket as well as environment, you need to optimize electricity consumption by refrigerator. Here is Top 5 quick tips to save electricity in refrigerator.
After few month of buying a brand new laptop or PC, it seems to become slower day by day. Time delay is very annoying in this super fast society. In this post we will focus on the cause and solution of this problem.
