When does a transistor turn on?

If there is no base current IB. flows, then locks the transistor. Its resistance in the collector-emitter path is infinite. The voltage at the collector-emitter is very high. If a base current flows, it becomes transistor conductive.

How does a PNP transistor work?

In principle a pnp transistor works just like an npn transistor. But since the zone sequence is different, i.e. emitter, base and collector are opposite to the npn transistor doped in the opposite direction, the current flows by means of other charge carriers! The majority holders in the pnp transistor are the electron holes.

What is an emitter?

Emitter or emitter (originally from Latin, to emitere “to send”) stands for: the source of radiation or a particle flow, as listed in emission.

Where can you find transistors?

Transistors are used in practically all electronic devices, be it in entertainment electronics (radio, television, PC) or in industry for amplifying, switching and controlling electrical signals.

What does a transistor amplify?

If a very small base current flows into the transistor, the transistor only "semiconducting", i.e. it doesn't just switch on, but "reinforced"the stream.

How does a transistor amplifier work?

A transistor amplifier is an electronic circuit that accepts a small input signal transistor controls which, due to its amplifying properties, emits a larger output signal (larger output current and / or larger output voltage).

How can you test transistors?

Remove the black probe and clip the red probe around the base. Hold the black probe on the emitter and collector. Compare the readings on your multimeter with what you saw before. If previously both times the value was high and now both values ​​are low is that transistor okay.

How is a microchip made?

A key step in the manufacture of Microchips consists in aligning light beams so precisely on a round plate of silicon, the wafer, that a pattern just a few nanometers fine is burned into it. This is how the foundation for the billions of transistors is poured.

How is a wafer made?

Both types are manufactured by sawing the appropriate ingots. Polycrystalline ingots are made from cuboid polycrystalline silicon blocks produced, from which the shape of the Wafer results (mostly square).

How does a microchip work?

Microchips are tiny platelets made of silicon. ... silicon is the most important semiconductor. A transistor is a switch that can be turned on (1) and off (0). It is contained in processors in millions and enables calculations in the binary system.

What does bc548 mean?

The NPN small-signal universal transistor BC548 is one of the most widely used transistors. The transistor can withstand a collector-emitter voltage of 30 V, a maximum power loss of 500 mW and a short-term peak current of 200 mA, but only 100 mA in the long run. ...

What does Wikipedia mean translated?

Surname. The name Wikipedia is a Box word consisting of "Wiki"And" Encyclopedia "(the English word for encyclopedia). The term "Wiki“Goes back to the Hawaiian word for 'fast'.
