In a parallel plate capacitor with air between the plates, each plate has an area of 6 xx 10^(-3) m^(2) and the distance between the plates is 3mm. Calculate the capcitanceof the capacitor. If this capacitor is connected to a 100V supply, what is the charge on each plate of hte capacitor? |

Answer» Solution :`A=6 xx 10^(-3) m^2` `d=3mm =3 xx 10^(-3)m` `C=(epsi_(0)A)/(d)=(8.85 xx 10^(-12) xx 6 xx 10^(-3))/(3 xx 10^(-3))=17.70 xx 106(-12)=17.7pF` `Q=CV=17.7 xx 10^(-12) xx 100=1.77 xx 10^(-9)C=1.77nC` |
