1. The problem statement, all variables and given/known data 2. Relevant equations I = E/(R sub_1 + R sub_2) 3. The attempt at a solution So I tried using the same approach for part a and it did not produce the same result. here's what i did: I sub_2 = E sub_2/(R sub_2 + R sub_3) E sub_2 was given as 1.7V I sub_2 = (1.7V)/(5) = .34 A <- answer for part b I also noticed E sub_3 was not given in the problem.
