# In a parallel plate capacitor with air between the plates, each plate has an area of 6 × 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?

Answer :

Given, A = 6 x 10^{-3} m^{2}

D = 3 mm = 3 x 10^{-3} m

Capacitance of the capacitor,

⇒ C = 1.77 x 10^{-11} F = 17.7 pF

When the capacitor is connected to a 100 V supply, the charge on the __each__ plate of the capacitor,

q = CV = 1.77 x 10^{-11} x 100 = 1.77 x 10^{-9} C
