Three resistors, 21, 43, and 73 , are connected in series, and a 0.55 A current passes through them. What is
(a) the equivalent resistance and
(b) the potential difference across the three resistors?
i tried to use EPE/q by putting the equivalent resistors/1.6E-6 charge. i dont think this is right though :/
The Attempt at a Solution
I got a as 137 and that is correct but i cant seem to get part b.
