Current resistance breaking around capital (5)
I believe the answer is:
accra
'capital' is the definition.
(capital of Ghana)
'current resistance breaking around' is the wordplay.
'current' becomes 'ac' (alternating current).
'resistance' becomes 'r' (electronics abbreviation).
'breaking' means one lot of letters goes inside another.
'around' becomes 'ca' (circa).
'r' going within 'ca' is 'cra'.
'ac'+'cra'='ACCRA'
(Other definitions for accra that I've seen before include "Main city of Ghana" , "Capital city of Ghana" , "foreign capital" , "Ghanaian capital" , "Ghanaian city" .)
