All the way to the left of the circuit, are a 1KΩ resistor and a 10KΩ resistor in parallel. These resistors in parallel set up a bias voltage for the PNP transistor. This allows for the PNP transistor to turn up and allows current flow from the emitter to the collector of the PNP ...
First lets talk about what atransistoris. These nifty chips revolutionized the electronics industry and you would be hardpressed to find something electronic that does not have at least a few thousand of these in them. So what do they do? They can control a flow of electrons by applying a ...
When a capacitor is actively charging up, the transistor that the capacitor is in series with will be OFF. This is the time when the corresponding LED will be OFF. When the capacitor then discharges to the base of the transistor it is in series with, this is when the transistor is on ...
Early transistors were huge compared to the transistors manufacturers produce today. The very first one was half an inch (1.3 centimeters) tall. But once engineers learned how to build a working transistor, the race was on to build them better and smaller. For the first few years, transistors...
10. THE TRANSISTOR CAN ACT LIKE A SWITCH (OR LIKE A PARTIALLY-ON SWITCH.) 11. CONNECT A POWER SUPPLY OR BATTERY FROM COLLECTOR TO EMITTER IN ORDER TO CREATE A BIG FLOW OF CHARGE (BUT WHY?) 12. THERE'S ANOTHER DEPLETION ZONE BETWEEN COLLECTOR AND BASE. ...
Transistor Q2 also acts as a power amplifier and feeds the frequency modulated audio signal to the antenna through capacitor C7. How to Build the Antenna A simple vertical antenna working against aground planewill suffice. But to be academically perfect, this would entail a sheet of conducting ma...
the base is another terminal of a transistor, and its main function is to control the current flow between the emitter and the collector. by applying a small current or voltage to the base, you can control a much larger current flowing through the transistor. what is the function of the ...
Here we’ll discuss only the continuous mode, which is the preferable way to operate a boost converter. Let’s evaluate the calculations involved with a boost converter in continuous mode: Inductor Current Build-Up (Transistor ON Phase)

Amplifiers boost the power of audio signals using transistors, which are made from semiconductors like silicon that have been modified through a process called doping. The transistor in an amplifier typically involves a three-layer structure with p-type and n-type semiconductors, allowing it to cont...
