berdasarkan data tersebut, besar daya listrik setiap alat adalah?

Maaf jawaban salah

P = W/t

P = W/t
Daya = Energi(kwh) : waktu(jam)

Caranya

•Lampu = 12000wh : 30hari : 12 × 3 = 225 watt
•Setrika = 12000wh : 30hr : 2 × 1 = 200watt
•TV = 36000wh : 30hr : 12 × 1 = 100watt
•KipasAngin = 45000wh : 30hr : 15 × 2 = 200watt

Jadi daya masing2 alat;
-Lampu pijar = 225 watt
-Setrika = 200 watt
-TV = 100 watt
-KipasAngin = 200 watt

semoga membantu :-)
