Question 1055605: Question: If the voltage, V, is an electric circuit is held constant, the current, I , is inversely proportional to the resistance, R. If the current is 420 milliamperes when the resistance is 2 ohms, find the current when the resistance is 12 ohms.
I solved this by +e=i%2Ar+
In which I did e=(420)(2) to get 840 then divided by the 12 ohms and I got 70 as my answer, but I'm not sure if this is correct.
