I am running a very simple RC circuit whose netlist is quoted below:
V0 n1 GND DC 10V
R1 n1 n2 3.3k
C2 n2 GND 47uF
However, when I plot for the voltage of the capacitor I get no charging curve. Instead I get a plotted result as if the capacitor instantly took its fully charged voltage value. I have tried several timesteps and capacitances and this problem is not solved. I am using revision 23 of ngspice.
The plot looks like this: http://i.imgur.com/q1I2s.png
