The diode is designed to work in Reverse bias but unlike zener diode it doesn't allow the flow of current in the reverse bias condition or mode. In fact, a varactor diode is designed to work as a variable capacitor. but how can we use a diode as a capacitor. Watch the full tutorial here

Instant pot is one of the most famous brands of kitchen appliances in the US market and dearest of millions of foodies.

Whether it’s pressure cooker, multi cooker, toaster or sauce wide, instantpot  appliances are always in the limelight.

This blog is all about air fryers.

Continue reading to discover everything about instant pot air fryers.Instant pot air fryer is an alternative to deep oil frying.

This is one of the best options for the people who like to eat crunchy and fried food but like to use less oil.

Air fryer is a multi use dry cooking appliance which provides you the same taste and crunchy texture like the deep fried food by using up to 95% less oil.

Electric current meaning is the movement of free electrons from one point to another.

An electron in an atom has an electric charge but it can’t contribute in the electric current until it leaves the atom (Read My Lecture on Electronics Materials to clear this concept).

 How to hide your ip address?how to hide my ip address?how to hide ip address for free?how to hide ip address from my ISP?And there are hundreds of such terms people ask from google each day.

Actually they want to hide their identity from government, surveillance agencies or from their ISP internet service provider.

The technical people really mean it but non technical people just want to hide their ip address to excess some content over the internet which is banned in their country.

And they get only one solution to it: use VPN.

Vpn is a virtual private network.

So they download vpn on their mobile phones or pcs without knowing the potential risks to their data and privacy are also coming with vpn service.

SCR (Silicon controlled rectifier or semiconductor controlled rectifier) is an electric device which comprises four pnpn layers with three major terminals anode, cathode and gate. The device has usage among hundreds of industrial products. Mainly the internal structure of SCR is similar to the most basic type of thyristor i.e  Shockley diode. If you want to understand SCR deeply, first you need to understand Shockley diode. we must have to grasp basic concepts regarding the function of shockley diode. That is why I will start this lecture with the working of Shockley diode.

What is a hexadecimal number system?Unlike decimal and binary numbers which use base 10 and 2 respectively.

Hexadecimal base or radix is 16.Hexadecimal refers to number 16.

Hexadecimal numbering system consists of 1st 10 digits from decimal numbers and the remaining 6 are represented by letters.

The following table shows the first sixteen hex numbers equivalent to decimal numbers.To read more go to hexadecimal

Every device on the network needs an IP address.

This IP address help you to identify your locaton in the network.

A static or fixed IP address does'nt change even if you are offline.

This can be dynamic or static IP.How to get static IP Address?You can contact your ISP to get a static IP.Is static IP address free?You have to pay extra money with your internet package to get a static IP.

The reason is IPv4 pool has alreday been exhuasted.

So companies use dynamic IPs to tackle the traffic on their networkDoes static IP address increase speed?IP address is just used to find your location so data can be transmitted to correct destination.

As you already know JFET and MOSFET both belong to the family of field effect transistors (FETs). They have plenty of advantages and applications in electronics. JFETs have two categories: n-channel JFET and p-channel JFET. The MOSFETs also have two categories enhancement MOSFET (E-MOSFET) and depletion MOSFET (D-MOSFET). These two categories are further divided into n-channel and p-channel types. To read full article click here or watch the full totorial

In this lecture I will guide you step-by-step on how you can make money online easily by doing just the copy paste job. Do a part time or full time job without any stress of less income and build your future life better. Then my friend Inam-ul-Haq Mansoor told me about a copy paste job work online without registration fee. But after doing some basic research, I came to know this is legitimate work and I can earn really good money by working remotely for just a few hours or days. So I started work on this site for more than a year and I found a pretty good increase in my net income per month. Now my desire to find permanent jobs has almost ended.

n a data communication system a signal is basically a physical form of data. The physical layer of the OSI model converts the data in the form of signals. Two nodes in a communication system exchange data in the form of signals.

For example in wireless communication the signal propagation is done via electromagnetic waves also known as radio waves, in optical fiber system the signal is a light wave. Similarly in a computer system signal is an electric current that takes the data from one point to another.

In this signal and systems lecture I will discuss classification of signals. In addition to this I will discuss signal characteristics

Multiplexing is the basis of today’s communication networks. Multiplexing is done to avoid interference and for maximum utilisation of the channel. There is a need of multiplexing not only within a network but outside the network too. In other words communication networks can’t work at the same time within the same space without multiplexing.

In this lecture I will explain JFET parameters. These parameters are mainly explained with the help of the drain characteristic curve of JFET. This is important because JFET characteristics and parameters can only be understood with the help of drain characteristics curve. So we will define the following terms 1. ohmic of JFET 2. active region of JFET 3. Breakdown region of JFET 4. pinch off voltage of JFET 5. cut off voltage of JFET 6. IDSS Watch the full lecture Before watching this video, I recommend you kindly watch my lecture on the working of JFET and then come on this lecture so you will have a better understanding of JFET parameters.

In this article I will discuss various types of computer keyboards and their uses in different applications. I will also recommend some keyboards available in the market. Today in the world of computer and information technology, everybody is familiar with the keyboards. Typically, a keyboard is a physical input device attached with a computer or laptop (in case of a touchscreen device keyboard is software based which appears on the screen) via some USB port. Computers keyboards are used for typing a document, to enter text data into the computer systems or to give commands in some cases. They can support English or any other language.

MOSFET is another type of transistor which is a sub-category of field effect transistor. MOSFET full form is “ Metal Oxide Semiconductor Field Effect Transistor”. Just like JFET, it has three terminals gate (G), source (S) and drain (D). There is an insulating layer of silicon dioxide (SiO2) between the gate and the channel. Watch the full tutorial below
