One spends their lifetime plugging things in. Be it either mobiles or laptop chargers or your television sets. But that’s all that’s about to change! There is no argument in that we humans love electricity. We love that stuff so much that you can get an idea about it just by walking out on the street. There is about trillions of money spent in setting up power stations and wires carrying electricity from where it is generated to our homes and offices.  Not only this. We love batteries too! An object that gives us power for a while before ending up in the garbage.  But then there is a negative aspect to all this. Wires and batteries are awful. Just think about it, overhead wires gets damaged in rough weathers and can lead to calamities that can claim a human life.  Plus imagine getting tangled in one of those wires under your computer desk. I know it’s pathetic.

A device which controls the current flowing into the channel on application of low-power electrical signal is called a transistor. Roughly, transistors can be classified as Bipolar Junction Transistors (BJTs) and Field Effect Transistors (FETs). In BJTs, a small amount of current is used to control the current flowing into the channel and hence BJTs are also known as current controlled devices. In FETs, a small voltage is used to control the current flowing and hence called as voltage controlled devices. This article briefs about the various types of FETs with a comparison chart. Let’s get started.

How cool it would be when devices on your workbench are interconnected? Creating a personal space for yourself where one of your devices acts as a server or a hub and allows you to access any information from any of your devices!! Sounds cool right? It would be super awesome when such connections are wireless. You can relish many facilities like Internet, GPRS, etc. All this has a technical term “Personal Area Network (PAN)”.
