a lot of electrical symbols, but you'll have to tell me what it looks like.

Of those 3, the one on the right is considered "earth ground", which is usually used in electrical wiring diagrams to represent a connection to true ground (a pole in the earth, a cold water pipe, or the common ground in a buildings wiring, which in turn goes out to the earth).

The one in the middle is the traditional American symbol for ground in an electrical or electronic device. Often a "common ground" rather than a connection the the earth. Also used in the US for "signal ground" which may or may not actually connect to an earth ground. (for example, the shield of a coax cable)

The one on the left is used in place of the middle one in Europe, and is also used in more modern drawings in the US for signal ground or common ground within electronic diagrams.

Went from not having a ground symbol... to needing to know what KIND of ground.. (earth, signal or common) :)
