Perhatikan rangkaian listrik arus searah di bawah ini. Hitung besar dayanya​

1/R.p = 1/6 + 1/12

1/Rp = (2+1)/12

Rp = 12/3

Rp = 4 ohm

Rs1 = Rp + 4 ohm = 4+4 = 8 ohm

Rs2 = 3 ohm + 5 ohm = 8 ohm

R.total =

1/R.tot = 1/Rs1 + 1/Rs2

1/R.tot= 1/8 + 1/8

R.tot= 8/2 = 4 ohm

kuat arus yg mengalir hamb.3 ohm =

I = V/R.tot = 12/4 = 3 Ampere

daya listrik =

P = V x I

P = 12 v x 3 A

P = 36 watt
