Homework Statement
Which of the following circuits could be reduced to a single resistance and a battery by determining the equivalent resistance using combinations of resistors in series and parallel?
A. II and IV only
B. I and II only
C. II and III only
D. I and III only
E. I and IV only
Homework Equations
Parallel: 1/Req = 1/R1+1/R2+...
Series: Req= R1+R2+...
The Attempt at a Solution
I think 3 and 4 can be eliminated because it seems impossible that you can reduce those to just one resistor.
So I'm thinking the answer is I and II only, but I'm unsure.
