Hi guys:
I have drawn a circuit and I would like to set the voltage of a resistor as a constant to figure out the input ac voltage and simulate a ac sweep to find out the input voltage characters with the input source frequency change.

Following is my circuit in which I would like set the electric potential of Rc1 as 1V then figure out the value of Vin, then do a ac sweep to take a look into to the relation between Vin of frequency, Could I do it in Pspice and how?

Its so graceful for any of your help

As your circuit has no active components the DC voltage across a resistor will not affect the AC performance.

What about I set the potential of Cn1 as 1V and figure out the input Voltage?
and please find the circuit in attachment[/img]
 

What you would normally do is make a DC sweep of Vin and find what value of Vin gives you 1V on Rc1. If that turned out to be 27.3V then you would do the AC sweep with Vin being set to 'DC 27.3 AC 1'.

However, I repeat, you have no active components so it will make no difference!
