-
BIt causes overloading and overheating of the socket/wiring, risking fire and voltage drop
-
CIt reduces the efficiency of appliances to zero
-
DIt reverses the polarity automatically
Answer
Correct Answer: It causes overloading and overheating of the socket/wiring, risking fire and voltage drop
Explanation
ReasonMultiple high-wattage devices draw excessive current through a single outlet, overheating cords/contacts and tripping breakers; fire hazard and voltage sag may result.
Final AnswerIt causes overloading and overheating of the socket/wiring, risking fire and voltage drop
