Jika R1=20 ohm, R2=15 ohm, dan R3=30 ohm, serta arus yg melalui R2=2 A, maka besar arus I dan tegangan V adalah

Diketahui =
R1 = 20 ohm
R2 = 15 ohm
R3 = 30 ohm
I2 = 2 A

Penyelesaian
*Mencari Tegangan ( V ) B - C
V ( B - C ) = I1 × R2 = 2 × 15 = 30 V

*Mencari Arus ( I1 )
I2 = V ( B - C ) /R3 = 30/30 = 1 A


_________________________
*Mencari Arus Total ( I total )
I1 + I2 = 2 + 1 = 3 A
_________________________



*Mencari Hambatan total ( R total )
R pararel + R seri ( R1 ) = 30 + 20 = 50 ohm


_________________________
* Mencari Tegangan ( V )
V = I total × R total = 3 × 50 = 150 V

Jawabannya
I = 3 Ampere
V = 150 Volt
