Jawaban:
59. It = 1 A
60. I = 1 A
Penjelasan:
59.
4 dan 4Ω di seri
Rs = 4 + 4 = 8 Ω
Rs dan 8Ω di paralel
Rp = ( 8. 8 ) / ( 8 + 8) = 64/16 = 4 Ω
Hambatan total
Rt = Rp + 2 = 4 + 2 = 6Ω
Arus total yang mengalir
It = ( 18 - 12 ) / Rt = 6/6 = 1 A
! Perhatikan baterai berlawanan arah jadi harus dikurangi.
60.
R1 dan R4 di seri
Rs = 1 + 5 = 6Ω
R2 dan Rs di paralel
Rp = R2. Rs/( R2 + Rs ) = 3. 6 / ( 3+6)
Rp = 18/9 = 2Ω
Rt = R1 + Rp = 2 + 2 = 4Ω
Arus yang mengalir
I = E/Rt = 4/4 = 1 A
