Dik = P1 = 4 x 25 = 100 t1 = 10 P2 = 100 t2 = 10 P3 = 50 t3 = 10
W1bulan = (100x10) + (100x10) + (50x10) x 30 = (1000 + 1000 + 500) x 30 = 2500 x 30 = 75000 Wh = 75 KWh 75 x 250.000 = 18750000 << yang harus dibayar 1 bulan

P1=25 w => 25:1000=0.025 kWh p2=100w=>100:1000=0.1 kWh p3=50w=>50:1000=0.5 kWh t=10 jam = 10 x 3600 = 36000 detik / 36000s jawab : p1+p2+p3 0.025+0.1+0.5 =0.625 kWh biaya uang harus dibayar adalah =0.625x Rp250.000 =Rp156.250 ~selesai~

lalu dikalikan 30 hari berarti Rp156.250x30 = Rp4,687,500
P1 = 4 x 25 = 100
t1 = 10
P2 = 100
t2 = 10
P3 = 50
t3 = 10
W1bulan = (100x10) + (100x10) + (50x10) x 30
= (1000 + 1000 + 500) x 30
= 2500 x 30
= 75000 Wh = 75 KWh
75 x 250.000 = 18750000 << yang harus dibayar 1 bulan
p2=100w=>100:1000=0.1 kWh
p3=50w=>50:1000=0.5 kWh
t=10 jam = 10 x 3600 = 36000 detik / 36000s
jawab : p1+p2+p3
0.025+0.1+0.5
=0.625 kWh
biaya uang harus dibayar adalah
=0.625x Rp250.000
=Rp156.250
