jika rangkaian pararel R1=12,R2=15,R3=1500 berapa Rt

dik : rangkaian paralel
R1 = 12 ohm, R2 = 15 ohm, R3 = 1500 ohm
dit : R total
Jawab :
1/R total = 1/R1 + 1/R2 + 1/R3
1/Rt = 1/12 + 1/15 + 1/1500

kpk dari 12,15,dan 1500 adalah 1500
12 × 125 = 1500
15 × 100 = 1500
1500 × 1 = 1500

1/Rt = 1(125)/12(125) + 1(100)/15(100) + 1(1)/1500(1)
1/Rt = 125/1500 + 100/1500 + 1/500
1/Rt = (125+100+1)/1500
1/Rt = 226/1500
Rt = 1500/226 = 6,6 ohm
