Question

Jika,
a) 1 microwave 700 watt digunakan selama 30 menit
b) 1 Toaster 650 watt digunakan selama 15 menit
Berapakah kWh nya ?

Answer 1

Diket :

P1 = 700 w
P2 = 650 w
t1 =30 menit = 0,5 jam
t2 = 15 menit = 0,25 jam

Dit : Energi kwh.....?


Jwb :

W = (P1 . t1) + (P2 . t2) / 1000
W = (700 . 0,5) + ( 650 . 0,25) / 1000
W = 350 + 162,5 / 1000
W = 512,5 / 1000
W = 0,5125 Kwh


Jadi Energinya sebesar 0,5125 Kwh
