Tinjauan Hukum Kirchoff I Hukum Kirchoff II
I1 + I2 = I3
Simpul A I1 + I2 = 1,8
I1 = 1,8 - I2 ..................................(1)
24 V - - 3.I1 + 2.I2 = 0
Loop I
24 - - 3 I1 + 2 I2 = 0 .....................................(2)
- 2.I2 - 7.I3 = 0
- 2 I2 - 7 I3 = 0
Loop II - 2 I2 7(1,8) = 0
- 2 I2 12,6 = 0
- 2 I2 = 12,6 ....................................................(3)
