Circuits' electronic error (5)
I believe the answer is:
lapse
'error' is the definition.
(lapse is a kind of error)
'circuits' electronic' is the wordplay.
'circuits'' becomes 'laps' ('lap' can be a synonym of 'circuit').
'electronic' becomes 'e' (as in e-mail or e-books).
'laps'+'e'='LAPSE'
(Other definitions for lapse that I've seen before include "Inadvertent error" , "Interval" , "A slight error or a passage of time" , "Fault" , "Careless mistake" .)
