Hi
I am trying to solve a Network problem in normalized form.
but found difficulty.
I have to calculate below mentioned variables.
Rp, Rn, Vp, Vn.
These are the variable which i need to calculate in normalized term.
can anyone tell how i can calculate the these parameter.
I tried with superposition theorem but not able to solved it.

What do you mean by "in normalized form/term". That might have one of several meanings.

You also need to show your best attempt, as far as you can get, so work the problem.

When no other values (voltages, currents) rae given you can choose these parameters as you want.
There is nothing to "calculate".

Actually here in this circuit.
I have to calculte the Rp and Rn in the form other mentioned parameter in the circuit above.
So if anyone have the best possible solution for this to solve.
Please tell

We do NOT do you homework for you. The starting point is YOU showing YOUR best attempt to work YOUR homework.

Hello,

You should first show how you would attempt to do this.

Without any additional information, what you would do is start by analyzing the circuit, then solve for whichever variable you need to calculate knowing the other variables.
In matrix form you can probably solve for all unknows with one matrix.
Sometimes you can eliminate one or more variables, but this circuit looks completely linear so that's probably not going to happen unless at least one of the variables happens to be some nonlinear function.
There's also a chance that one or more variables may have more than one solution although it does not look that way at first glance. An example would be two resistors directly in parallel. That would mean you could solve for the total parallel resistance but then all you could do is mention the range of the two values or the formula for the total parallel resistance.

Do you have to calculate 2 things, Vp and Vn, or 4 things, Vp, Vn, Rp, Rn?
When you say "in the form", do you mean a symbolic solution?

Yes I have to calculate the values of Rp and Rn, but these should be in the form of symbolic parameter.
Vp and Vn is the node voltage with respect to earth.
and you can consider R1=R2.

And, again, YOU need to show YOUR best attempt to work YOUR homework problem as far as you can. We will not just do your homework for you.

A good and detailed answer requires a good and clear question.
Therefore, in your case. the question could be:

"How to express the symbols Rp and Rn as a function of the following variables......." ?

Please be aware that you cannot "calculate the values of Rp and Rn" , unless the values for the other parts in the circuit are known

You can solve for any and all variables symbolically or numerically by simply doing a regular Nodal Analysis or even some other method. You can determine if there are many solutions or no solutions or just one unique solution after that.
Matrix methods or just a set of simultaneous equations.

What kinds of analysis have you done in the past?
