Worked for the electricity man (5)
I believe the answer is:
acted
'worked' is the definition.
('act' can be a synonym of 'work')
'the electricity man' is the wordplay.
'the electricity' becomes 'ac' (AC is an example).
'man' becomes 'ted' (Ted is a man's name**).
'ac'+'ted'='ACTED'
'for' is the link.
(Other definitions for acted that I've seen before include "Appeared in play" , "Posed as" , "Behaved or played a part" , "Behaved or performed" , "Took part in play" .)
