I had a question in physics that was as follows:
0.5 >>>>1 (ignore the >>, included to
1 >>>>>4 Show grid)
(Current and resistance may have been something else but I can't remember what) the question was, is current proportional to resistance? I now know the answer is Current is proportional to the root of resistance (y ∝ √x), with k being 1/2 (y=K√x). The problem is this was a guess and I don't know how to actually work it out, can anyone explain? Thankyou!

Current is denoted by I, resistance is denoted by R.
The way you know that I is proportional to the square root of R is that for each time you multiply R by 4, I is multiplied by 2.
