tolong di jawab please
Jawaban:
1.
R1 dan R2 diseri
Ra = 20+10 = 30
R3 dan R4 diseri
Rb = 40+20 = 60
Ra dan Rb diparalel
1/R = 1/30 + 1/60 = 2/60 + 1/60 = 3/60
R = 60/3 = 20 ohm
2.
R2 R3 dan R4 diseri
Ra = 10 + 20 + 30 = 60
Ra dan R5 diparalel
1/Rb = 1/60 + 1/60 = 2/60
Rb = 60/2 = 30
Rb dan R1 dan R6 diseri
R = 30 + 10 + 15 = 55 ohm
