Remote just lacking current (3)
I believe the answer is:
far
'remote' is the definition.
('far' can be a synonym of 'remote')
'just lacking current' is the wordplay.
'just' becomes 'fair' ('fair' is associated in meaning with 'just').
'lacking' is a deletion indicator.
'current' becomes 'i' (symbol for electric current).
'fair' with 'i' taken out is 'FAR'.
(Other definitions for far that I've seen before include "Very much" , "At a great distance way" , "Remote" , "A long, long way to go" , "Distant" .)
