besar arus I yg mengalir pada rangkaian adalah

R pararel = 6×3 / 6+3 = 18/9 = 2 ohm

R total = 2+4 = 6 ohm

I = V / R
I = 6/6
I = 1 A

Menentukan Kuat Arus (I)

Rumus
1/Rp = 1/R1 + 1/R2
Rt (Rs) = Rp + R3
I = V / Rt

Penyelesaian
cari dahulu Rt (hambatan total)
1/Rp = 1/3 + 1/6
1/Rp = 2 + 1 / 6
1/Rp = 3/6
Rp = 6/3 = 2 ohm

Rt (Rs) = 2 ohm + 4 ohm
Rt = 6 ohm

Jika sudah dapat Rt, maka I dapat kita cari
I = V / Rt
I = 6 V / 6 ohm
I = 1 A
