Question 270812
I=E/R+nr Solve for h
-----
Two questions?
1. Do you mean "solve for "n"?
2. Is only the R in the denominator
or is R+nr in the denominator under E?
-------------
I=E/R+nr solve for R 
Sorry I had it entered incorrectly.
R+nr is in the denominator under E
-----
I = E/(R+nr)
---
R + nr = E/I
---
R = [E/I] - nr
