Ponder resistance: choose to embrace force (7)
I believe the answer is:
reflect
'ponder' is the definition.
(I know that ponder can be written as reflect)
'resistance choose to embrace force' is the wordplay.
'resistance' becomes 'r' (electronics abbreviation).
'choose' becomes 'elect' (electing is a kind of choosing).
'to embrace' indicates putting letters inside.
'force' becomes 'F' (symbol used in Physics e.g. f=ma).
'elect' placed around 'f' is 'eflect'.
'r'+'eflect'='REFLECT'
(Other definitions for reflect that I've seen before include "Think or cast light" , "Meditate - mirror - show" , "Bend or turn back" , "Ponder or throw back an image" , "Display" .)
