a dielectric of dielectric constant 3 fills three fourth of the space between the plates of a parallel plate capacitor. What percentage of the energy is stored in the dielectric.
The Attempt at a Solution
When dielectric is introduced the above equation changes to epsilon0AV2/(d-t+t/epsilonr)
I substituted 3d/4 for t since dielectric fills three fourth of space between the plates of capacitor and 3 for relative permeability.
When simplified i got the answer epsilon0AV2/d
which is twice the value of U that is 2U
In the book the answer is given as 50% which i don't understand. How this 50% comes? Thanks in advance, revered members
