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.

The resistance of a given current conductor  (ohms) in a circuit  DOES  NOT  DEPEND  on current.

Voltage does depend,  but not resistance.

From the Physics point of view, this wording sounds as if nail scratching on glass.
