An air filled parallel plate capacitor is to be constructed which can store 12 C of charge when operated at 1200 V.What can be the minimum plate area of the capacitor? The dielectric strengh of air is 3 X 106 V/m..

Hey mastermind890 , I got the solution !!! I was confused why dielectric srength is given . But when I read the theory , I understood . Dielectruc strength is the min. E at which breakdown occurs . Now , E =Q/AEo ( E=electric field b/w plates ) When E is minimum , then A is maximum . therefore , A =Q/EEo Put values , and we get the answer as 0.45 m2 . I hope u understood !!!!!

I had already understood the problem..
Anyways thanx for the answer...
so here is my salute........
try to answer my other post on capacitance..

find the equvalent capacitance between a and b in tems of c1,c2,c3? please do this with series and parallel combination?dont confuse with dotted lines they all are straight?question frm hc verma2 page 158 c1 c2 ____|_|____________|_|______ | | | | | | i dont know how to make the di _a____| |___ | agram plz see hc vema pg 158 | |___ c3 |____b | | | |____|_|_____|_________|_|___| c2 c1

Hey prathika ! I was also confused by the way the author has solved the que. . I tried to do this by series - parallel method , but couldn't . Then I asked my teacher , and he advised me to avoid such hard lengthy subjective problems , as these r never asked in competitive exams . So , I hav left this que. . But still , if u get to know the solution , then pls tell me !!!!!
