Concerned with a measure of potential rising (6)
I believe the answer is:
revolt
'rising' is the definition.
(synonyms)
'concerned with a measure of potential' is the wordplay.
'concerned with' becomes 're' (re can mean regarding, concerning).
'a measure of potential' becomes 'volt' (unit of electric potential).
're'+'volt'='REVOLT'
(Other definitions for revolt that I've seen before include "Uprising, insurrection" , "Mutiny or disgust" , "Rise in rebellion" , "Rebel or disgust" , "Organised opposition to authority" .)
