SUMMARY
The discussion centers on the absence of current in the right loop of a circuit involving an inductor, as outlined in problem 2 of the AP Physics C exam. The key reason is that the current through an inductor is defined by the integral of voltage over time, specifically expressed as i = ∫(v(t)/L) dt + i(t_0). At the moment the switch S closes, the initial current i(t_0) is zero because the switch was previously open, resulting in no current flowing through the right loop immediately after the switch is closed.
