"Capacitor loop with no resistance" ? In Circuit Simulator at http://falstad.com/circuit/ I created a circuit attached below which refuses to run because "capacitor loop with no resistance". To me it seems that there is no problem with this circuit and that the two capacitors will simply act as an equivalent capacitor of capacitors in parallel. They would charge up and that would be the end of that. What am I missing? The reason I'm posting here is that I assume there is that this is due to my lack of understanding of the physics of the situation rather than some bug.
