Jumlah Kwh sebulan

Di rumah, saya memiliki 1 lampu 18 watt menyala 5 jam sehari, 1 seterika 350 watt menyala 2 jam sehari, 6 lampu 20 watt menyala 20 jam sehari, 1 lampu 15 watt menyala 15 jam sehari, 1 kipas angin 20 watt menyala 20 jam sehari, 1 TV 350 watt menyala 18 jam sehari, 1 kulkas 150 watt menyala 24 jam sehari, 1 magic jar 75 watt menyala 20 jam sehari, dan 1 kipas angin 35 watt menyala 22 jam sehari. Hitunglah:

  1. Jumlah Kwh sehari
  2. Jumlah Kwh sebulan
  3. Biaya 1 bulan jika 1Kwh Rp 200,-

JAWAB:

Diketahui:

W1 = 1 x 18 x 5 = 90 watt jam = 0,09 Kwh

W2 = 1 x 350 x 2 = 700 watt jam = 0,7 Kwh

W3 = 6 x 20 x 20 = 2400 watt jam = 2,4 Kwh

W4 = 1 x 15 x 15 = 225 watt jam = 0,225 Kwh

W5 = 1 x 20 x 20 = 400 watt jam = 0,4 Kwh

W6 = 1 x 350 x18 = 6300 watt jam = 6,3 Kwh

W7 = 1 x 150 x 24 = 3600 watt jam = 3,6 Kwh

W8 = 1 x75 x 20 = 1500 watt jam = 1,5 Kwh

W9 = 1 x 35 x 22 = 770 watt jam = 0,77 Kwh

Ditanyakan:

a. Kwh sehari

b. Kwh sebulan

c. Biaya 1 bulan jika 1 Kwh = Rp 200,-

Dijawab:

a. 0,09+0,7+2,4+0,225+0,4+6,3+3,6+1,5+0,77 = 15,985 Kwh

b. 15,985 x 30 hari = 479,55 Kwh

c. Kwh sebulan x 200

= 479,55 x 200 = Rp 95.910,-

Jadi, setiap bulan saya membayar listrik kira- kira Rp 95.910,-
