The membrane of a living cell can be approximated by a parallel-plate capacitor with plates of area 4.75 x 10-9 m2, a plate separation of 8.5 x 10-9 m, and a dielectric with a dielectric constant of 4.5. (a) What is the energy stored in such a cell membrane if the potential difference across it is 0.0725 V? (b) Would your answer to part (a) increase, decrease, or stay the same if the thickness of the cell membrane is increased? Explain.

Answer #1

PS :i have mentioned here thickness dosnt effect the energy of the parallel plate capacitor energy. But While changing the thickness of capacitor plate, if distance between capacitor plates changes then energy also changes.

PS: Please share any doubts here for further discussion
