Penjelasan:

1. tersusun seri

R seri = 2 + 3 + 4

R seri = 9 Ohm

arus rangkaian (i) :

I = V/R

I = 36/9

I = 4 A

b. Tegangan pada R1,R2,dan R3

Arus pada R1, R2,R3 adalah 4 A

VR1 = I.R

VR1 = 4 × 2

VR1 = 8 Volt

VR2 = I.R

VR2 = 4 × 3

VR2 = 12 Volt

VR3 = I.R

VR3 = 4 × 4

VR3 = 16 Volt

2. Tersusun paralel

1/Rp = 1/3 + 1/6 + 1/4

1/Rp = 4/12 + 2/12 + 3/12

1/Rp = 9/12 Ohm

Rp = 12/9 Ohm

a. arus rangkaian (i)

I = V/R

I = 12 : 12/8

I = 9 A

b. arus I1

perbandingan arus I1 : I2 : I3

= 4 : 2 : 3

arus I1

= 4/4+2+3 × I tot

= 4/9 × 9

= 4 Ampere

c. Arus I2

= 2/9 × 9

= 2 Ampere

d. arus I3

= 3/9 × 9

= 3 Ampere
