Question

2) Figure 2 illustrates a composite object comprising first and second solid cylindrical conductors connected end to end. The first cylinder has length LI, uniform x-sectional area Aı, and uniform resistivity pi. The 2nd cylinder has length L2, uniform x-sectional area A2, and uniform resistivity p2. The terminals of an ideal L. P Figure 2 A, A, battery having emf E are connected to the opposing ends of the object. Determine expressions for the following quantities {Li, Ai, a) the current flowing through the object; and b) value of the potential at the interface between the cylinders (assuming the potential is zero at the
