I am currently doing AS level physics at school. However I still can't rearrange formula for questions. I literally have no idea on how to go about doing it. For example, a simple formula like R=V/I I tried to rearrange it so I could find I. I tried using an example I found on this forum, so I did it like this: RxV=V/IxV=I so therefore I=RxV. However I know this is completely wrong so can someone please help me to understand how to rearrange formulas. I know that you are meant to do the opposite of what is in the forula e.g if there is division, you times it and vice versa. So please someone help me before I fail really badly.
