Yang diketahui :E1 = 10 V
R1 = 4 ohm
R2 = 2 ohm
E2 = 12 V
R3 = 1 ohm
Yang ditanya I1, I2 dan I3.
Pembahasan.
Dengan menggunakan hukum II kirchoff :
Loop I.
I1 R1 + I3 R2 = 10
I1 4 + I3 2 = 10
4 I1 + 2 I3 = 10
2 I1 + I3 = 5 ... (1)
Loop II.
I2 R3 + I3 R2 = 12
I2 1 + I3 2 = 12
I2 + 2 I3 = 12 ... (2)
Hukum I kirchof :
I3 = I1 + I2
I2 = I3 - I1 .... (3)
Subtitusikan (3) ke (2)
I2 + 2 I3 = 12
(I3 - I1) + 2 I3 = 12
3 I3 - I1 = 12 ... (4)
Eliminasikan (1) dan (4)
2 I1 + I3 = 5
3 I3 - I1 = 12
(1) dikali 3
(4) dikali 1
Menjadi
6 I1 + 3 I3 = 15
3 I3 - I1 = 12
—————— -
7 I1 = 3
I1 = 3/7 ... (a)
Subtitusikan (a) ke (4)
3 I3 - I1 = 12
3 I3 - 3/7 = 12
21 I3 - 3 = 87
21 I3 = 87 + 3
21 I3 = 90
I3 = 90/21
I3 = 30/7
Subtitusikan (b) ke (3)
I2 = I3 - I1
I2 = 30/7 - 3/7
I2 = 27/7
Kesimpulan.
I1 = 3/7 A
I2 = 27/7 A
I3 = 30/7 A
