P = 50 watt V = 110 volt T = 12 jam/hari Per KWH Rp 1.550,- Hitung sewa satu bulan!

Materi : Listrik Dinamis

Jawab : W = P. t
W = 50 watt . 12 jam
W = 600 watt / 0,6 kWh
harga sewa 1 bulan
= 30 . 0,6 . 1.550
= Rp. 27.900

semoga membantu ^^

diket ;
P = 50 w
V = 110 v
t = 12 jam / hr
tarif = Rp 1550
dit : biaya 1 bln 30 hr
Jwb :
# total energi 1 bln
W = P . t . 30
W = 50 . 12 . 30
W = 18.000 wh = 18 kwh

# biaya
biaya = W . tarif
biaya = 18 . 1550
biaya = Rp 27.900
