Question: Two connections allow contact with two circuit elements in series inside a box, but it is not known whether the circuit elements are R, L,

Two connections allow contact with two circuit elements in series inside a box, but it is not known whether the circuit elements are R, L, or C. In an attempt to find what is inside the box, you make some measurements, with the following results: when a 3.0-V DC power supply is connected across the terminals, a maximum direct current of 300 mA is measured in the circuit after a suitably long time. When a 60-Hz source with maximum voltage of 3.0 V is connected instead, the maximum current is measured as 200 mA.
(a) What are the two elements in the box?
(b) What are their values of R, L, or C?
