Infatuated about current girl (4)

Ross

I believe the answer is:

maid

I'm a little stuck... Click here to teach me more about this clue!

'girl' is the definition.
(maid is a kind of girl)

'infatuated about current' is the wordplay.
'infatuated' becomes 'mad' (I can't explain this - if you can you should believe this answer much more).
'about' means one lot of letters goes inside another.
'current' becomes 'I' (symbol for electric current).
'mad' enclosing 'i' is 'MAID'.

Can you help me to learn more?

(Other definitions for maid that I've seen before include "One in service" , "Damsel" , "- - -of-all-work" , "Female domestic servant" , "daughter?" .)

I've seen this clue in The Telegraph.
