Question

Tentang rangkaian listrik. mohon bantuannya

Answer 1

R total
pertama rangkaian seri dijumlah
R1+R3 = 12 ohm + 4 ohm = 16 ohm
kemudian paralel dg R2
1/R2+1/R = 1/6 + 1/16 = 11/48
R total = 48/11= 4,364 ohm

Arus Total
I = V/Rtotal
  = 12 V / 4,364 ohm
  = 2,75 A

Arus di R2
V1 = V2
I₂R₂ = Itotal (Rtotal)
I₂    = Itotal (Rtotal) /R₂
      = (2,75 A) (4,364 ohm) / (6 ohm)
      = 2 A
