Bantuannya dong kak pake caranya ya... makasihhh

R1 = 20 ohm
R2 = 30 ohm
R3 = 10 om
I = 2 A

Pararel :
1/Rp = 1/R1 + 1/R2
1/Rp = 1/20 + 1/30
1/Rp = 3/60 + 2/60
1/Rp = 5/60
Rp = 60/5
Rp = 12 ohm

Seri :
Rs = Rp + R3
Rs = 12 + 10
Rs = 22 ohm

V = I × Rs
V = 2 × 22
V = 44 volt

Jadi beda potensial (V) adalah 44 volt (C)
