The above figure shows a parallel plate capacitor, where the plate area is A = 34 cm? and plate seperation is d = 37 mm. The dielectric constants
k1, k2, kz are respectively 5.9,4.1, 4.2. Here, a = 27 mm
a) Calculate the effective dielectric constant.
Effective dielectric constant
Give your answer up to at least three significance digits.
b) If this capacitor is connected to a battery with EMF E = 11 Volts, then calculate the amount of charge present in positively charged plate only.
Charge
Give your answer up to at least three significance digits.
C
c) Now, suppose all the 3 dielectric materials are removed. If the battery remains connected then what will be the stored energy of the capacitor.
Energy
Give your answer up to at least three significance digits.
