What is a transistor? How does a transistor work? Part 1
Why people recommend it
Explains how to use a transistor in practice, as a resistor controlled by the base rather than through semiconductor physics; liked by learners put off by textbooks.
Watch for: the resistor analogy is a simplification
In their words
Here is a really good series of videos on transistors: one and two.

In this very interesting introductive video [video], I learned that a transistor is basically nothing more than a resistor whose value changes accordingly to what's applied at the Base.
