Joint Entrance Examination/2000 Screening/Q023 capcitors and dielectric, equivalent capcitance

Welcome to the Highschool Help Forum! The forum is currently in "Beta" stage of development. You can ask questions and answer/discuss them. The basic functionalities are present. What's required is a more aesthetic look to the Static pages and a more user friendly setup. This will happen over the time gradually as we start creating some content. The site has a lot of tools, like posting mathematical calculations, images and diagrams; categorizing questions and so on. Having them here is NO GOOD unless you know how to use them. I am thoroughly against compiling a list of these features and then writing about them. As soon as you do not understand how to do something or use a certain feature, report that on "How To"s Section of the forum. Your queries will be answered there. If you have any ideas/discussion regarding the site/comments, please go to Discussions regarding Highschool Help Forum Lastly, thanks for joining in the site's development process! It matters!

Original Question by Dharav talk Here's the question... A parallel plate capaciter of area A, plate separation d and capacitance C is filled with three different dielectric materials having dielectric constants k1, k2 and k3 as shown. If a single dielectric material is to be used to have the same capacitance C in this capacitor then its dielectric constant k is given by... ${\frac {1}{k}}={\frac {1}{k_{1}}}+{\frac {1}{k_{2}}}+{\frac {1}{2k_{3}}}$ ${\frac {1}{k}}={\frac {1}{k_{1}+k_{2}}}+{\frac {1}{2k_{3}}}$ ${\frac {1}{k}}={\frac {k_{1}k_{2}}{k_{1}+k_{2}}}+{\frac {1}{k_{2}}}+{2k_{3}}$ ${\frac {1}{k}}={\frac {k_{3}k_{1}}{k_{1}+k_{2}}}+{\frac {k_{2}k_{3}}{k_{2}+k_{3}}}$ Posted by Dharav talk 05:08, 18 August 2009 (UTC)
