hi guys i have no idea on how to solve this because of the air being an Insulator so please help me solve this : calculate the area of the plate used for making a capacitor 1f if the length between the plates equals 10mm and the insulator is air ? i have on idea on how to solve this so anything will help me a lot thanks in advance
Hi Zanec, No offence intended but I think you need to read up on what a capacitor is and how it works. All capacitors have an insulator of some sort called the dielectric, sandwiched between two "plates". Capacitance is proportional to the surface area of overlap of the two "plates" and inversely proportional to the distance between them.It is also proportional to the "dielectric strength" of the material between them. Due to the great efforts of some AAC members (not including me) there is a great resource on this site, called the e-book,and the links are on the top of each page. The section on capacitors is here http://www.allaboutcircuits.com/vol_1/chpt_13/index.html Like yourself, my knowledge of electronics is limited and I have found it a great help
For a formula for the capacitance of a parallel plate capacitor and lots more interesting stuff, see:- http://hyperphysics.phy-astr.gsu.edu/hbase/electric/pplate.html#c1 Basically depends on the area of the plates, distance between the plates and the dialectric constant of the material between the plates.
