Hello everyone, i'm confused on what i'm suppose to do here...the problem says: R1 = 100 . R2 = R3 = 45.0 . R4 = 75.0 , and the ideal battery has emf = 6.00 V. Here is the image: http://www.webassign.net/hrw/27-42.gif Here is the question: (a) What is the equivalent resistance? 117.31 (b) What is i in R1? .051 (c) What is i in R2? (d) What is i in R3? A (e) What is i in R4? A Okay i got (a) and (b), but messed up (c) like alot of times... I tred i = E/R1+R2, i = .051, and a few others, all wrong...any ideas what i'm doing wrong?
