Adaptable electric current feeding factory (6)
I believe the answer is:
pliant
'adaptable' is the definition.
(I've seen this before)
'electric current feeding factory' is the wordplay.
'electric current' becomes 'i' (physics symbol).
'feeding' indicates putting letters inside.
'factory' becomes 'plant' (I've seen this before).
'i' going inside 'plant' is 'PLIANT'.
(Other definitions for pliant that I've seen before include "Supple or flexible" , "Plastic" , "Adaptable" , "Not firm" , "Malleable, flexible" .)
