A) In the left figure, the switch is closed; current flows through both resistors (resulting in voltage V1 and V2), and charges the capacitor. In the right figure, the switch is open; current (discharge of the capacitor) only flows through the first resistor resulting in voltage V1, which would decay exponentially, and no current flows through the second resistor. B)An idealized signal that would be produced by a current interruption experiment.
