A pair of identical resistors is arranged first in series and then in parallel. The resistors in series are attached to a power supply, producing a current of $I_s$. The parallel arrangement is then attached to the same power supply, and the supplied current is $I_p$. Find the ratio $\frac{I_s}{I_p}$?
