HOW DO TRANSISTORS WORK? PART II©1995William J. Beaty, BSEE Physics? That's where you find new insights on things people have been thinking about for a long time. If you don't have two or three separate approaches to explaining something, then you don't really understand it. ...
A transistor is a kind of semiconductor device that controls current. Its function is to amplify the weak signal into an electrical signal with a larger amplitude value, and it is also used as a contactless switch. How do Transistors work?
Instead, you could do it through arelay. But even the relay usually needs more current than the pin can provide. So you’d need a transistor to control the relay: Connect left side of the resistor to an output pin (ex from Arduino) to control the relay But transistors are also useful ...
A BJT is one of the most common types of transistors and can be either NPN or PNP. This means a BJT consists of three terminals: the emitter, the base and the collector. By joining these three layers, a BJT can amplify an electrical signal and switch the current on and off. Two kind...

Before we start, it should be noted that we’ll be using the transistor as a simple switch and not as an amplifier. Remember, transistors can operate either as an amplifier or a switch. If you’re using a transistor to amplify a signal, the transistor is said to be operating in the ...
V2 is the final stage of amplification and its purpose is to amplify for power (voltage x current) where V1A and V1B were focused on voltage amplification. The signal enters the power tube at pin 5 (grid) and leaves via pin 3 (plate). It then goes to the output transformer (OT) ...
By creating a sine wave and running it through a wire, you create a simple radio transmitter. It is extremely easy to create a sine wave with just a few electronic components — acapacitorand aninductorcan create the sine wave, and a couple of transistors can amplify the wave into a powe...
applications, particularly in electronic devices. For example, p-type and n-type semiconductors are used in the construction of diodes and transistors. Diodes are electrical components that allow current to flow in one direction and not the other, while transistors amplify and switch electronic ...
