I'm trying to understand how fractions relate in total resistance. You have parrell circuits. Each one has a 2 ohm resistor on it. FOr if you go by the law 1/total resistance = N/sum of resistances. SO that gives us 1/total=2/1 It we make the 2 a 1 that means the 1 becomes 1/2. SO that means Total=1/1/2. But I did and equation and the total should equal 2. SO do I just avoind the 1 and put 2 or do I include it in 1/2?
