Disappears without current giving illusions (7)

I believe the answer is:

facades

'illusions' is the definition.
(I've seen this in another clue)

'disappears without current' is the wordplay.
'disappears' becomes 'fades' (fading is a kind of disappearing).
'without' indicates putting letters inside ('without' can be similar in meaning to 'outside').
'current' becomes 'ac' (alternating current).
'fades' enclosing 'ac' is 'FACADES'.

'giving' is the link.

(Another definition for facades that I've seen is " Fronts of buildings".)

I've seen this clue in the Sydney Morning Herald.
