R = 80 ohm
ditanya: P?
jawab:
karna rumusnya gak ada jdi dicari dlu V nya
V = I x R
V = 0,2 x 80
V = 16 V
ditanya
P = V x I
P = 16 x 0.2
P = 3.2 watt
2. diketahui: V = 6 V
R = 12 Ohm
ditanya : P?
jawab:
P = V²/R
P= (6)² / 12
P= 36/ 12
P= 3 watt
3. diketahui:
a. 2 lampu: 10 watt menyala 10 jam
b. 3 lampu: 15 watt menyala 8 jam
c. 1 setrika : 350 watt menyala 2 jam
ditanya: tagihan?
jawab:
a. 2 x 10 x 10 = 200 wh
b. 3 x 15 x 8 = 360 wh
c. 350 x 2 = 700 wh
=> 200 + 360 + 700 = 1.260/ 1000 = 1,26 kwh
=> 1,26 x 30 = 37,8
pembayarn: 37,8 x 500 = Rp18.900
biaya beban = Rp20.000 - Rp18.900 = Rp1,100
maaf klo jwban nmr 3 salah
