BJT Water Analogy

The BJT Water Analogy is a way of understanding how Bipolar Junction Transistors (BJTs) work.

The analogy compares the three terminals of a BJT to three points in a water system: the base, the collector, and the emitter.

The base is the input terminal, the collector is the output terminal, and the emitter is the ground terminal.

When the base is biased, it allows electrons to flow from the emitter to the collector.

This is similar to how water flows from a higher point to a lower point in a water system.

The BJT Water Analogy is a helpful way to visualize how BJTs work.
