In a paralllel plate capacitor with air between the plates , each plate has an area of `6xx10^-3m^2` and the distance between the plates is 3 m m. Calculate the capacitance of the capacitor. If this capacitor is connected to a 100 V supply , what is the charge on each plate of the capacitor ?

Explanation

Here `A=6xx10^-3m^2,d=3mm=3xx10^-3m,C=?`
`V=100V,q=?`
`C_(o) =(epsi_0A)/(d)=((8.85xx10^-12)(6xx10^-3))/(3xx10^-3)`
`=1.77xx10^-11F`
`q=C_oV=1.77xx10^-11xx100=1.77xx10^-9C`.
