I have a parallel circuit RC circuit connected in series with a resistor R1, Ac voltage is connected to one end of R1 circuit. Dc source is connected to another end of RC circuit. How can we analyse the circuit.
ac voltage-r1-Parallel RC -Dc supply-circuit close.
I want to calculate the voltage across RC circuit.

 

Please post a schematic.

Is this homework?

Is this homework?

No it is not, I am trying to understand the logic of how the circuit works. attached the schematic

 

It looks like the circuit that would be used to measure the AC mains voltage on an A/D with 0-5V input.

 

Hi M,
One point, if you are using that circuit in simulation, the bottom end of V2 is not connected.

yes

bottom end of V2 is conected

 

bottom end of V2 is conected

see there is a node in bottom connection

 

Hi M,
As I understand the connection point of two wires, it has to be a defined large 'dot'
Note the colour of a connected and unconnected point, Green to Green, not Brown to Green

Ok but the dc voltage is connected. I have corrected it. can you help me in analysing the circuit?

 

hi M,
For which V1 frequency and amplitude do you want to determine the voltage across C1 and R2?
E

hi M,
For which V1 frequency and amplitude do you want to determine the voltage across C1 and R2?
E

For V1 = 230Vac and frequency = 60 Hz

 

Hi M,
Do you know how to calculate the Impedance of C1 at 60Hz?
E

 

yes it will Xc =1/wC = 26.5k ohm

 

Hi M,
Check this AAC link for the R || C value.

Hi E,
I have gone through this link, I can calculate the parallel Impedance of Parallel RC. Impedance would be Z=
(2.68 x 10^3)−227.38j

Now the question still remains as what would be the voltage across RC circuit and Dc voltage source.

And series resistor and parallel Rc circuit would be Z total = (1.17268 x 10^6)−227.38j

The easiest way to find that is to use superposition. Are you familiar with that analysis technique?

yes I know that but I am not able to solve that. Can you please tell me.
