Choose right laudatory work for conductor (9)
I believe the answer is:
electrode
'for conductor' is the definition.
(electrode is a kind of conductor)
'choose right laudatory work' is the wordplay.
'choose' becomes 'elect' (electing is a kind of choosing).
'right' becomes 'r' (abbreviation).
'laudatory work' becomes 'ode' (I've seen this in another clue).
'elect'+'r'+'ode'='ELECTRODE'
(Other definitions for electrode that I've seen before include "Conductor by which current enters" , "Conducting terminal" , "Connecting conductor" , "Conductor for electricity as it enters or leaves" , "Terminal of, eg, an acid battery" .)
