Current demand for applause (7)
I believe the answer is:
acclaim
'applause' is the definition.
(I've seen this before)
'current demand' is the wordplay.
'current' becomes 'ac' (alternating current).
'demand' becomes 'claim' (claim is a kind of demand).
'ac'+'claim'='ACCLAIM'
'for' acts as a link.
(Other definitions for acclaim that I've seen before include "Hail" , "Enthusiastic and public praise" , "Laud" , "commendation" , "Credit" .)
