Tolongg dong pake caranya lengkap,poin dapet 10 kalo ga bisa gak usah jwb

A. I = V/R
= 20 / (1+2+3)
= 20 / 6
= 3, 33.. Ampere

b. 1/Rp = 1/2 + 1/3
= 3/6 + 2/6
= 5/6
Rp = 6/5
= 1, 2 ohm
Rtotal = 1,2 + 1
= 2,2 ohm
I = V/R
= 20/ 2,2
= 9,09… Ampere

c. 1/Rp = 1/1 + 1/2 + 1/3
= 6/6 + 3/6 + 2/6
= 11/6
Rp = 6/11
= 0,54… ohm

I = V/R
= 20 : 11/6
= 20 x 6/11
= 10,909… Ampere

d. 1/Rp = 1/1 + 1/2
= 2/2 + 1/2
= 3/2
Rp = 2/3
= 0,666… ohm
Rtotal = 2/3 + 3
= 2/3 + 9/3
= 11/3
= 3,66… ohm

I = V/R
= 20 : 11/3
= 20 x 3/11
= 5,45… Ampere
