Asked by BLESSED
A capacitor is made from two 1.2 cm diameter coins separated by a 0.18 mm thick piece of paper (K = 3.7). A 6 V battery is connected to the capacitor. How much charge is on each coin?
My solution:
C= K * Permitivity * A/d = q/v
I solved for q and got 1.2 X 10^-10
But i still got it wrong. Can someone please check and see where i went wrong or check to see if you arrive at a different answer

Area = 1.131*10^-4 m^2
d = 1.8*10^-4 m
epsilon = 8.85*10^-12
C = 2.06*10^-11 F
q = CV = 1.2*10^-10 coulombs
I agree with your answer
