Question

stating proportionality
The original statement is "current is inversely proportional to resistance". Could you also say "resistance is inversely proportional to current" ?

Does it also apply to other proportions ?

Answer 1

Yes to the 1st part. If current (I) is inversely proportional to resistance (R) then resistance is also inversely proportional to current.
$$
I=\cfrac{k}{R}
$$
where k is a constant.
Now solving for R:
$$
R=\cfrac{k}{I}
$$
Which shows that resistance is inversely proportional to current.

This also shows that this must be true for all proportions with this inverse relationship if you take R to be an arbitrary variable that is inversely proportional to I.
