Rtotal = R45 = 5 ohm
R2 + r45 + r6 + r7 = 35 ohm
Ra-l = 10×35/10+35 = 350/45 = 7,77 ohm
Rtot = 10 + 7,77 = 17,77 = 17,78
ltotal = v/Rtotal
= 10,7/17,78 = 0,6A
R45 = 5 ohm
R38= 5 ohm
Ratas = r38 + r45 + r6 + r7
Rbawah = 10 ohm
30×10/30+10 = 7,5
rtot = 10 + 7,5 = 17,5
Itot = 10/17,5 = 10,57
= 0,55A
1/rp = 1/30 + 1/30 = 2/30
= 1/15
1/10 + 1/10 = 2/10 = 1/5
1/15 = 1/15
1/5 = 3/15
1/rp = 1+3/15 = 4/15
rp = 15/4 = 3.75 ohm
rtot = 10 + 3.75 + 10
= 23,75
I = V/R = 10/23,75
= 6,42
