Problems in electronics for starters causing confusion (3)
I believe the answer is:
pie
'confusion' is the definition.
(I've seen this in other clues)
'problems in electronics for starters' is the wordplay.
'for starters' suggests taking the first letters.
The initial letters of 'problems in electronics' is 'PIE'.
'causing' acts as a link.
(Other definitions for pie that I've seen before include "Easy thing" , "what to cook for dinner?" , "Irrational things to do with circles and logs" , "steak might go in this" , "Pasty - former Indian coin - mixed type - bird" .)
