A small current can turn a larger current on and off. A silicon chip is a piece of silicon that can hold thousands of transistors. With transistors acting as switches, you can create Boolean gates, and with Boolean gates you can create microprocessor chips. The natural progression from ...
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. ...
http://www.satcure-focus.com/tutor/page4.htmHow do Transistors Work?Thousands of textbooks have been written to explain electronics and I haven't found a single one that can explain the operation of a transistor. They all make it seem so complicated!Let's see if I can do better. Here...
Why Do You Need A Transistor? A common question I get is why do we need the transistor? Why not connect the LED and resistor directly to the battery? The advantage of a transistor is that you can use a small current or voltage to control a much larger current and voltage. ...
Regardless of the type, the basic principles of charge carrier behavior, doping, and junction operation make transistors such a powerful tool in electronics. Semiconductors and Transistors Semiconductors are the foundation of modern electronics due to their electrical conductivity, which falls between ...
the project you have in mind and the power you'll need to make it work. Your EL wire's length determines how much power you'll need, and the power you use determines how bright your EL wire will appear. Using an inverter that's too small in relation to the length of the wire will...
Transistors had many advantages: high reliability, low power consumption and small size compared to tubes or relays. These transistors were discrete devices, meaning that each transistor was a separate device. Each one came in a little metal can about the size of a pea with three wires attached...
In the above post we elaborately learned how to connect transistors in parallel. We can summarize the procedure as I have explained below: When bipolar transistors are connected in parallel, always make sure to add a calculated emitter resistor for each transistor. This resistor enables the BJTs ...
you also separate the microphone from the speaker and so help to reduce "buzzing" and "whistling" (where the speaker effectively feeds back into the microphone). In 1943, for example, several years before transistors completely revolutionized the power of hearing aids, we have Zenith Electronics ...
