    I am reading about transistor action and trying to understand this diagram:


    I've seen the 3-lined symbol at the bottom of the diagram everywhere. Originally I thought this symbol meant ground, and from my reading, it seems it still does. However, ground doesn't always mean a connection to something grounded. In this diagram, does the 3-lined symbol mean the negative connection to the DC power source (assuming this is using a dc power source)? And if so, does that mean that the electrons flow up into this circuit from the 3-lined symbol?

    Yes, ground is really just a reference point for 0V. Generally, electrons do travel from the ground or negative terminal.
