The bill you pay from your current account? (11)
I believe the answer is:
electricity
'your current account?' is the definition.
I can't judge whether this defines the answer.
'the bill you pay' is the wordplay.
'the bill' becomes 'electric' (electric bill is a kind of bill).
'you pay' becomes 'ity' (I am not sure about this - if you are sure you should believe this answer much more).
'electric'+'ity'='ELECTRICITY'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for electricity that I've seen before include "Energy associated with charged particles" , "Energy from movement of charged particles" , "Current supplier" , "One form of energy" , "Domestic energy supply" .)
