Hi The current (I) in an electric circuit is inversely proportional to the resistance (R). I varies INVERSELY as R That is: I = k/R I = .2amp when R = 10ohms .2amp = k/ 10ohms, k = .2amps•10ohms = 2amps•ohms find R when I = 1.2amp I = k/R 0r R = k/I R = (2amps•ohms)/(1.2amps) = 1 2/3 ohms Wish You the Best in your Studies.
