Code cracked by resistance reveals scheme (5)
I believe the answer is:
decor
'scheme' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'code cracked by resistance' is the wordplay.
'cracked' is an anagram indicator.
'by' means one lot of letters go next to another.
'resistance' becomes 'r' (electronics abbreviation).
'code' is an anagram of 'deco'.
'deco'+'r'='DECOR'
'reveals' acts as a link.
Can you help me to learn more?
(Other definitions for decor that I've seen before include "Furnishings and colours of a room" , "(Room) design" , "Interior colour scheme and furnishing" , "Choice of colour" , "Interior layout and furnishings" .)
