Connected with electricity (5)
I believe the answer is:
wired
'connected' is the definition.
(similar in meaning)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for wired that I've seen before include "Bugged" , "set up for broadcast?" , "Using cables; tense, edgy" , "Sent a telegram" , "having Internet connection" .)
