Itungin dong bro ............

Mecin cuci :
E listrik = P x t
12 kWh = P x 2 x 30
12000 = P x 2 x30
P = 200 Watt

TV  :
Elistrik = P x t
19,2 kWh = P x 8 x 30
19200 = P x 8 x 30
P = 80 Watt

AC : 
Elistrik = P x t
72 kWh = P x 6 x 30
72000 = P x 6 x 30
P = 400 Watt

Semoga membantu dan tolong jadikan jawaban terbaik ya
