1. The problem statement, all variables and given/known data Given three 4 ohms resistors rated at 20 W, find the maximum potential difference that can be applied if they are connected all in parallel... 2. Relevant equations 3. The attempt at a solution so in this case i first calculated the current using P= I^2R, which gives I=2.24 A. Like at first, i used V=IR and just plugged in the values for the current I just found and 4 ohms for the resistor, and i got the right answer, which is 8.94 V...but then i started double guessing myself, like i was wondering why exactly did we not divide the current by 3 seeing as though the resistors are in parallel with the same resistance values?...Does it have something to do with the fact that they are asking for the maximum potential difference?
