This circuit uses a P-FET – to turn the power on, open the FET by bringing the GATE signal down to ground level, and to switch it off, close the FET by bringing the GATE back up, where the ...

That said, the FET is a fascinating device. Join us as we take an in-depth look at their operation, and how and where you might use one. A diagram of an n-channel JFET. As the negative gate ...

and the gate acts as controller. These elements work differently in the two main types of transistor used today: bipolar junction transistors, which came first, and the metal-oxide-semiconductor field ...
