Answer 1

Jawaban:

1.

W = P t

W = 50 watt x 1 jam = 50 wH = 0,050 kwH

Biaya = 0,050 kwH x Rp 1352 /kwH = Rp 67,6

dalam satuan joule, jam ke detik

1 jam = 3600 s

W = 50 watt x 1 jam x 3600 s = 180000 Joule

2.

W = 70 x 2 = 140 = 0,140 kwH

Biaya = 0,140 x 1352 = Rp 189,3

dlm joule

W = 70 x 2 x 3600 = 504000 J

3.

W = 70 x 3 = 210 = 0,210 kwH

Biaya = 0,210 x 1352 = Rp 283,9

W = 70 x 3 x 3600 = 756000 J

4.

W = 260 x 4 = 1040 = 1,04 kwH

Biaya = 1,04 x 1352 = Rp 106

W = 260 x 4 x 3600 = 3744000 J
