Question

dielectric constant 4, as shown in the figure. The capacity of the capacitor changes to
a) 25 u F
b) 20 uF
K-4
c) 40 uF
d) 5uF
Consider a parallel plate capacitor of 10uF (micro-farad) with air filled in the gap between
the plates. Now one half of the space between the plates is filled with a dielectric of​
