The effective resistance of a parallel connection that consists of four wires of equal length, equal area of cross-section and same material is $0.25\ \Omega$. What will be the effective resistance if they are connected in series ?
Answer: (A) $4\ \Omega$
Parallel: $\dfrac{R}{4} = 0.25$, so each wire has $R = 1\ \Omega$.
Series: $4R = 4\ \Omega$.
