What electronics use transistors?
What electronics use transistors?
A transistor is most commonly used as either electronic switches in digital circuits or as an amplifier.
Do all electronics use transistors?
Deeply embedded in almost everything electronic, transistors have become the nerve cells of the Information Age.
How transistors work in computers?
A transistor is a miniature electronic component that can do two different jobs. A tiny electric current flowing through one part of a transistor can make a much bigger current flow through another part of it. In other words, the small current switches on the larger one. This is essentially how all computer chips work.
How do you make a small electronic project?

How many PN junction has a transistor?
two PN junctions
The Transistor is a three terminal solid state device which is formed by connecting two diodes back to back. Hence it has got two PN junctions.
How transistors work as an amplifier?
A transistor acts as an amplifier by raising the strength of a weak signal. The DC bias voltage applied to the emitter base junction, makes it remain in forward biased condition. Thus a small input voltage results in a large output voltage, which shows that the transistor works as an amplifier.

How big are modern transistors?
Modern silicon commercial transistors may be smaller than 45 nanometers in size. They’re so small that NVDIA ‘s new graphics card (codenamed GF100 ) has more than 3 billion transistors, the most ever jammed into one chip.
What was the first transistor?
The first high-frequency transistor was the surface-barrier germanium transistor developed by Philco in 1953, capable of operating up to 60 MHz . These were made by etching depressions into an N-type germanium base from both sides with jets of Indium (III) sulfate until it was a few ten-thousandths of an inch thick.
Does a transistor have resistance?
A resistor is a passive component and a transistor is active. A resistor has a fixed resistance that does not depend on signal polarity or amplitude. It just sits there and does it’s job, so it’s called passive. A transistor resistance varies depending on an applied control signal.
