hitunglah nilai hambatan pengganti dari setiap gambar rangkaian berikut!

diket. R1=5 ohm
R2=10 ohm
R3=3 ohm
R4=6 ohm
R5=15 ohm
dit. R pengganti (Rp)/ R total (Rs)
jawab:
A. Rs = R1+R2+R3
=5+10+3
=18 ohm
B. Rs1=R1+R2+R3 =5+10+3=18 ohm
Rs2=R4+R5 =6+15=21 ohm
1/Rp =1/Rs1 + 1/Rs2
=1/18+1/21 = 21/378 + 18/378
=39/378
Rp=378/39
=9,69 ohm
C. 1/Rp = 1/R2 +1/R3+1/R4
=1/10 + 1/3 +1/6
=3/30+10/30+5/30
=18/30
Rp=30/18 =1,66 ohm
Rs = R1+Rp + R5
=5+1,66+15
=21,66 ohm
D. Rs1=R1+R2=5+10=15 ohm
Rs2=R3+R4+R5=3+6+15=24 ohm
1/Rp =1/Rs1+1/Rs2
=1/15+1/24 =8/120+5/120
=13/120
Rp=120/13
=9,23 ohm
