I am not sure how to best help you. Suppose guitar is in standard tuning E-A-D-G-B-e. Now if you place a capo at the first fret, the open strings at Capo 1 become F-Bb-Eb-Ab-C-f. The open chords also transpose up 1/2 step so if you play what looks like an E chord, it becomes and F, G becomes Ab, A becomes Bb, C becomes Db, D becomes Eb etc.
At Capo 2 (2nd fret), the strings wouod be F#-B-E-A-C#-f# and the open chord shapes would be one whole step higher than if played sans capo: E becomes F#, G becomes A, A becomes B, C becomes D, D becomes E etc.
at Capo 4, you would be up two whole steps. E becomes G#, G becomes B, A becomes C#, C becomes E, D becomes F#. Learning where the roots are in each chord shape and learning where notes are on the fretboard will help you see these things for yourself.
Does this help you?
