Calculation of R,C in Physical Design

[manikanta.9332]

Hi all,

How to calculate R,C values with out Using Lookup Tables?

How to calculate R,C values By using A Wire?

Thanks.......

I think you need to provide more info on what you are trying to do, your question is too vague.

please elaborate

Hi all,

if a wire is given its resistance by getting R = rho x (L/A) it is given by Resistance per Unit length. In the case of a Capasitstanse How it is Caliculated for a wire .

Did you try to google "wire capacitence"?

Hi all,

I get the the Coaxial cable i am not get Wire capacitance for metal wires?

Thanks.............

Capacitance is defined between insulated conductors, f.i. two wires, two metal plates, the center conductor and the shield of a coaxial cable, etc.

The capacitance of a single wire not referred to any other object makes no sense.
For a single wire you can, instead, define the self-inductance.
