Question

Tolong bantuin donk...

Answer 1

1.
diketahui :
V1= 12 Volt
V2 = 12 volt
R1 = 2 ohm
R2 = 1ohm
R3 = 6 ohm

ditanyakan :
I = ?

jawab :
V1+v2 = I (R1+R2+R3)
12+12 = I (2+1+6)
24 = 9 I
I = 24/9 = 8/3 A

2.
diketahui :
R1 = 1 ohm
R2 = 3 ohm
R3 = 6 ohm
V = 6 volt

ditanyakan :
I pada R2 = ?

jawab :
1/Rp = 1/R2+1/R3 = 1/6 + 1/3 = 1/6 + 2/6 = 3/6
Rp = 2 ohm

Rt = R1 + Rp
Rt = 1+2 = 3 0hm

It = V/Rt = 6/3 = 2 A
V pada R2,3 = I x Rp = 2 x 2 = 4 volt

I pada R2 = V2,3/R2 = 4/3 = 1,33 A


3.
diketahui :
R1 = 4 ohm
R2 = 4 ohm
R3 = 8 ohm
V = 40 Volt

ditanyakan :
1/Rp = 1/R1 + 1/R2 = 1/4 + 1/4 = 2/4
Rp = 2 ohm

Rt = Rp + R3 = 2 + 8 = 10 ohm

It = V/Rt = 40/10 = 4 A

V1.,2 = It x Rp
V1.,2 = 4 x 2 = 8 V

I 1 = V1,2/ R1 = 8/4 = 2 A
