Two conducting strips connected in series carrying current I.
Two flat metal strips, Strip A and Strip B, are connected in series in a circuit carrying a steady current. Strip A has a cross-sectional area \(A\) and a free-electron density \(n\). Strip B has a cross-sectional area \(2A\) and a free-electron density \(3n\). What is the ratio \(\dfrac{v_{\text{A}}}{v_{\text{B}}}\) of the average drift speed of free electrons in Strip A to that in Strip B?
