Hello all!

I am really stuck up here. I have made this circuit and want to measure the voltage across the capacitor. The voltage should gradually increase as the capacitor charges, and then become constant. But, I only get a constant voltage of 6V across the capacitor.

Infact, I have to measure the time constant. I am doing a transient analysis, and when I plot the voltage, it just shows a straight line, and no rising trend.

Please help!

Have you done voltage divider theory, and do you know how a capacitor 'see's' a DC supply?
 
Thanks for the reply.

I have solved the problem. I was not setting the initial condition of the capacitor to 0V.
