This tester is primarily meant to test bipolar transistors. It can indicate the type of the transistor as well as identify its base, collector and emitter pins. The circuit is very simple. The ...

The circuit has been designed for transistors to determine whether the pin is emitter, base or collector as well as the type if NPN or PNP polarity, and can also be used in testing diodes. 4011 – a ...

How many remote controls do you have in your home? Don’t you wish all these things were better integrated somehow, or that you could add remote control functionality to a random device? It’s a common ...

A transistor is a key component in electronics, often used as a switch or to amplify a signal from a sensor. NPN (negative-positive-negative) transistors are the most used transistor. An illustration ...

The sandwich transistor was William Shockley's brainchild. It's also called the junction transistor. While the rest of the lab was busy researching Bardeen and Brattain's point-contact transistor, ...
