n resistors, each of resistance R are first connected in series and then in parallel. What is the ratio of the total effective resistance of the circuit in the series to the parallel combination?

Text Solution

Verified by Experts

In the series combination, `R_s = nR`
In the parallel combination, `R_p = R/n`
`:. R_s/R_p =(nR)/(R//n) =n^2`
