How to calculate effective capacitance Ceff

[chinnisunny]

Hi,

If two wires are running parallel to eachother how do we calculate the effective capacitance?Ceff.

This is one of the interview question that i was asked recently.

Your help and inputs will be appreciated.

Thanks.

Dear Friend,

Effictive Capacitance is

The sum of Coupling Capacitance+ Cross over capacitance

Coupling cap is the capcitance from the one wire to another wire

Cross over cap is the cap from one of the wire to array of wire crossing it

Hi,

Thanks for the answer.
Is there any particular formula to calculate Ceff?
