Need to switch ... for transistor switching? [Ben Krasnow] put together a tutorial in which he does an excellent job of explaining the ins and outs of designing transistor control circuits.

In theory, the hundreds of photons, controlled by the triggering photon, could fan out and switch off hundreds of other transistors in an optical circuit. With its exotic clouds of atoms and bulky ...

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use ... when you want to switch a voltage instead of a ground. There are also certain amplifier ...

Here is the circuit of an ultra sensitive IR receiver that can be used to switch on various AC devices through an ... it conducts taking the base of T2 to ground potential. T2 is a PNP transistor so ...

The transistor is probably ... device that could amplify or switch an electric current. This simple device can be used to create complex electronic circuits, and although there are other types ...
