Let's go...

In the late 1940s, American scientists Shockley, Bardeen and Brattain conducted research on contacts with semiconductors. They discovered that this can be used to amplify a signal. The discovery was named "Transfer Resistor", short transistor, and was awarded the Nobel Prize for Physics in 1956.

The following twenty years were used to further develope transistors. However, for a long time there was doubt whether the transistor would prevail as an electronic component. Only in the 1960s, with the first transistor radios, came the breakthrough.

Here you can learn how transistors work. However, it does not explain how a transistor works interally. This topic is discussed in "Transistor" in the section semiconductor physics.

In this first part you get to know the two types of bipolar junction transistors. In simple circuits you discover the main features and discover how transistors are connected.

The second part (Go on...) describes another five experiments. In them you learn about applications of transistors.

Let's go...and have fun...
