Try this simple experiment to clearly know how does a transistor work in electronic circuits. A small current when applied to the base of a transistor, a relatively huge current is allowed to pass through its collector to the emitter.
How Does A Transistor Work? Atransistorworks by controlling the flow of current through a semiconductor material. The current is controlled by the voltage applied to the transistor’s base.Transistorscan be used as switches or amplifiers. When used as a switch, the transistor can be turned on ...
It can be seen that the DC signal of the collector of the transistor in the amplifier circuit does not change with the input signal and the AC signal changes with the input signal. In the amplification process, the collector AC signal is superimposed on the DC signal, and only the AC sig...
The emitter, base and collector have the same functions in a PNP circuit. The only difference in the PNP transistor is that the n-type base is layered between the p-type emitter and collector. The NPN versus PNP configurations determine the direction of the emitter's arrow, which is always...
The transistor is in virtually every electronic device we use: TV's, radios, Tamagotchis. But how does it work? Well the basic principle is actually incredibly simple. It works just like this switch, so it controls the flow of electric current. It can be off, so you could call that ...
When I first became interested in electronics as a kid, I sat down and figured out how bipolar transistors work. Well, sort of. I read many articles which explained the "Common Base" amplifier. Common-base is the setup which was used by the inventors of the transistor. In those explanatio...
Symbol of PNP Transistor How Does a PNP Transistor Work The positive terminal of avoltage source(VEB) is connected with Emitter (P-type) and the negative terminal is connected with the Base terminal (N-type). Therefore, the Emitter-Base junction is connected in forward bias. ...
R2 is there to limit the current to the LED. You can choose the value you would have chosen if you were to connect the LED and resistor directly to the 9V battery, without the transistor. For example, 1 kΩ should work fine.

They're illuminated solely by the movement of electrons in a semiconductor material, and they last just as long as a standard transistor. The life span of an LED surpasses the short life of an incandescent bulb by thousands of hours. Because of these advantages, tiny LEDs are one of the ...
