IP Cell Membranes The membrane of a living cell can be approximated by a parallel-plate capacitor with plates of area 4.80×10−9 m2 , a plate separation of 8.3×10−9 m , and a dielectric with a dielectric constant of 4.4. Part A What is the energy stored in such a cell membrane if the potential difference across it is 7.55×10−2 V ? Express your answer using two significant figures. U = nothing J Request Answer Part B Would your answer to part A increase, decrease, or stay the same if the thickness of the cell membrane is increased?
