2.8) In a parallel plate capacitor with air between the plates, each plate has an area of 6 \times 10^{-3}m^{2} and the distance between the plates is 3 mm. 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?

Given,

Area of the capacitor plate A = 6 \times 10^{-3}m^{2}

Distance between the plates d=3mm

Now,

Capacitance of the parallel plate capacitor is

C=\frac{\epsilon_0 A}{d}

\epsilon _0= permittivity of  free space =  8.854*10^{-12}N^{-1}m^{-2}C^{_2}

putting all know value we get,

C=\frac{8.854*10^{-12}*6*10^{-3}}{3*10^{-3}}=17.71*10^{-12}F=17.71pF

Hence capacitance of the capacitor is 17.71pF.

Now,

Charge on the plate of the capacitor :

Q=CV=17.71*10^{-12}*100=1.771*10^{-9}C

Hence charge on each plate of the capacitor is 1.771*10^{-9}C.
