Nomor 16 caranya gimana ?

Setrika
18 kWh / (30 x 1) = 18000 Wh / (30 x 1) = 600 Wh
P = E / t = 600 Wh / (2 h) = 300 W

Lampu
30 kWh / (30 x 5) = 30000 Wh / (30 x 5) = 200 Wh
P = E / t = 200 Wh / (10 h) = 20 W

tv
22,5 kWh / (30 x 1) = 22500 Wh / (30 x 1) = 750 Wh
P = E / t = 750 Wh / (5 h) = 150 W

Pompa air
15 kWh / (30 x 1) = 15000 Wh / (30 x 1) = 500 Wh
P = E / t = 500 Wh / (2 h) = 250 W
