14. Buat tabel list : 3 lampu @10 W : 30 W --> 30 x 12 jam = 360 Wh 2 lampu @ 40 W : 80 W --> 80 x 6 jam = 480 Wh TV : 60 W --> 60 x 8 jam = 480 Wh ------------------------ + 1320 Wh
Total Energi 1 bulan = 1320 x 30 hari = 39.600 Wh = 39,6 Kwh
Biaya = Rp.1500/kwh x 39,6 Kwh = Rp. 59.400
16. Arus I dan Jumlah lilitan berbanding terbalik :
1. ρ = m / V ---> m = ρ. V = 3500 kg/m³ . 700 cm³ --> 1 cm³ = 1/100.00.00 m³ = 3500. 700/ 1.000.000 = 2,450 Kg atau = 2450 gr
