jika R1=20 ohm,R3=15 ohm,dan R3=30 ohm,serta arus yang 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

Jawab :

# Tegangan ( V ) B - C
V ( B - C ) = I1 × R2 = 2 × 15 = 30 V

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

#Arus Total ( I total )
I1 + I2 = 2 + 1 = 3 A

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

# Tegangan ( V )
V = I total × R total = 3 × 20 = 60 V

Jadi,
I = 3 Ampere
V = 60 Volt

semoga membantu
