Knife Pleated Kilts Knife pleating (or side pleating) is the most commonly used pleating style for kilts today -- so much so that most Highland Dress enthusiasts are barely aware that other pleating styles are possible.
A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power.It is composed of semiconductor material with at least three terminals for connection to an external circuit.he transistor provides current gain, allowing a relatively large current in the collector to be switched by a much smaller current into the base terminal. The ratio of these currents varies depending on the type of transistor, and even for a particular type, varies depending on the collector current.
Types of transistor. There are two types of standard (bipolar junction) transistors, NPN and PNP, with different circuit symbols. The letters refer to the layers of semiconductor material used to make the transistor. Most transistors used today are NPN because this is the easiest type to make from silicon.here are two types of standard (bipolar junction) transistors, NPN and PNP, with different circuit symbols.
