the transistor does not “amplify” the input voltage (VIN) in any way. To use a transistor as a switch, all you have to do is increase the current at the base terminal to a certain level, and the transistor
Transistor switches find use in the control of lamps, motors, and relays Fully ON transistors operate in the saturation region while fully OFF transistors operate in cut-off regions For the transistor to operate as a switch, a principle of the small base current controlling the large collector ...
Start by locating the marking beneath or close to the transistor. Search for a line, an arrow, or a triangle with sides as well as a line beneath that appears to link them. Unless the PCB transistor lacks that line, use that line which comes out from the left like the base. The ...
Another big advantage of a MOSFET against the BJT is it's high input resistance, which makes it possible to be integrated with any logic IC directly, no matter how big the load may be that's being switched by the device. This advantage also allows us to connect many MOSFETs in parallel ...
The transistor is a simple component that you can use to build a lot of fun projects. In this hands-on guide, you’ll learn how transistors work so that you can use them in your next circuit. And it’s actually pretty easy, once you learn the basics. I’ll focus on the two most...
letting electricity enter or leave. A small change in the current or voltage at this layer produces a large, rapid change in the current passing through the entire component, enabling the transistor to function. This change occurs at the junction of both the n-type and p-type layers, also ...
Each time a cell goes through an erase cycle, some charge is left in the floating-gate transistor, which changes its resistance. As the resistance builds, the amount of current required to change the gate increases. Eventually, the gate can't be flipped at all, rendering it useless. This ...

As per the Fig. the LED can be switched ON and Off by applying a small voltage (>0.6 ) to the free end of the 10 K resistor or the ‘Base’ of the transistor. For testing purpose you can use the positive supply itself to toggle the LED. Though this voltage may look quite large,...
