All capacitors in figure are fully charged and there is no charge nsfer between the capacitors. If the potential difference ween the plates of C2 is 10V, what is the charge on C7 ? a)86μC b)480μC c)360μC d)214μC e)288μC

A large capacitance of 2.00mF is needed for a certain application. (a) Caloulate the area the parallel plates of such a capacitor must have if they are separated by 4.00 μm of Tefion _____m2

a) A capacitor consists of two parallel metal plates immersed in a high-dielectric liquid, chloro- cyclohexane (e = 30). When the separation of the plates is 1mm, the capacitance is 0.06 F. Initially it is charged, at 500 V. Assume that 0 = 8.85 x 10-12 Fm-1. i) == Use this information to calculate the area of the plates, and the charge and the energy stored. ii) The plates are now pulled apart, to a gap of 1cm. Calculate the voltage it is now at, the energy now stored, and the force required to pull the plates apart.
