Demonstrating the need for - and effects of - a DC path to ground from every node in a circuit 02. This simulation runs because there is a DC path to ground from node B through Rdcpath1 so the simulator can find a set of steady state DC initial conditions around the circuit. However, because the DC voltage source has been replaced with a PULSE source generating a 1V step it gives voltages across the capacitors that are correctly defined by the ratio of the capacitors. Note that for this simulation to give accurate answers, the product of Rdcpath1*C must be much longer than the simulation stop time. Try reducing the value of RDCPATH1 to see what happens as Rdcpath1*C becomes comparable to the simulation stop time. Try moving RDCPATH1 so that it is reconnected from node B to node A. Then try adding a second DC path resistor RDCPATH2 connected from node B to ground to see what happens. See what effect changing the resistor values has.
