Again, an ideal diode 1-V characteristic can be assumed to have a reverse-bias saturation current, Is = 10-15 A, or you should use a 1N4001 rectifier diode if you use the simulator''s graphic interface (for steps for adding the 1N4001 rectifier diode to your schematic, see the supplementary instructions at the end of the pre-lab).
For a given capacitor, the ratio of the charge stored in the capacitor to the voltage difference between the plates of the capacitor always remains the same.

Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open. If the voltage is changing rapidly, the current will be high and the capacitor behaves more like a short.
