Current Electricity

The effective resistance of a parallel connection that consists of four wires of equal length, equal area of cross-section and the same material is $0.25Ω$ . What will be the effective resistance if they are connected in series?

A. $0.25Ω$
B. $0.5Ω$
C. $1Ω$
D. $4Ω$ ✓

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
