diketahui R1: 10 ohm, R2 : 5 ohm ,R3 : 7 ohm, R4: 6 ohm,dengan E : 20 volt,ditanya I,I1,I2,I3...?

diket. R1=10 ohm
R2=5 ohm
R3=7 ohm
R4=6 ohm
E(V)=20 v
dit. I , I1 , I2, I3 ,I4 ?

1/Rp=1/R1+1/R2+1/R3+1/R4
=1/10+1/5+1/7+1/6
=21/210+42/210+30/210+35/210
=128/210
R =210/128=1,64 ohm

I = V / R = 20 / 1,64 =12,19 A
I1=V/ R1 =20 / 10 = 2 A
I2 = V /R2 = 20/ 5 = 4 A
I 3=V / R 3 = 20/7 = 2,85 A
I4=V/R4=20/6 = 3,33A
