What is true of it
Esus4 is E, A and B — 1, 4 and 5 counted from E.
These are also the notes of Asus2/E. Which name is right depends on what is underneath and what came before — the notes alone do not decide.
The easiest of the 5 fingerings below is 002200: 2 fingers, held at the 2nd fret.
3 of them use open strings, which is what makes a shape quiet to change to.
Where its notes are on the neck
The brass dots are E, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
