R1 = 100 . R2 = R3 = 45.0 . R4 = 75.0 , and the ideal battery has emf = 6.00 V.

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?
