Besarnya hambatan total dari rangkaian listrik tersebut adalah..

jawab
R2+R3 =(4+4)ohm = 8 ohm

1/Rp=1/8 + 1/8 ohm
1/Rp=2/8 ohm
1/Rp=1/4 ohm

Rp=4 ohm

R(total)=Rp+R4

=4 ohm + 3 ohm
=7 ohm

maav bila salah

[tex]Rs1=4+4=8\\ Rs2=3+1=4\\ R1\ dan\ rs1\ diparalelkan=\frac {1}{8}+\frac {1}{8}\\ =\frac {2}{8}\\ Rp1=4\ \\ rp1\ dan\ rs2\ diserikan\\ 4+4=8\\ \_____________ _ __[/tex]
