When You Close the Switch S in the Figure, the Potential

Multiple Choice

When you close the switch S in the figure, the potential between A and B drops to zero. The current in the top loop does not immediately drop to zero because

A) the top loop has less resistance than the bottom loop.
B) an EMF is generated in the inductor L.
C) an EMF is generated in the resistor R.
D) the current depends only on the resistance in the circuit.
E) Kirchhoff's junction rule states that the current into a junction must equal the current out of the junction.
