Homework Help: Capacitance calculation

  1. Nov 26, 2009 #1
    Dear Sir,

    I would like to know the origin for the following formula for capacitance. A text book which describes this formula will be better so that I can buy it.

    Please see the attachment for better understanding.





    C= (2*pi*Epsilon o* Epsilon r* l)/ln(2*h)/r were A=pi*r*r

    with best regards,
    Sandhi Prashant kumar
