The fluids inside and outside a cell are good conductors separated by the cell wall, which is a dielectric. Thus the cell has capacitance; charge may be stored on its inner and outer surfaces (see the figure below). It is a good approximation to treat the thin charged layer as a parallel-plate capacitor. Typically the wall is 9.50 x 10-9 m thick and has a dielectric constant of 5.00. (everybody's responses to this question before were incorrect so I need...

Nerve cells maintain a charge separation across their cell membrane.
PLEASE ANSWER WITH UNITSNerve cells maintain a charge separation across their cell membrane. The cell membrane in a particular cell is 13 nm thick and the cell can be modeled as a cylinder with a diameter of 11 um and a length of 90 um. If the potential difference across the cell membrane is 50 mV, what is the charge stored on the cell? (Assume that the dielectric constant of the cell membrane is 1.0.)

A typical cell has an electric potential difference across its cell membrane, The electric potential interior to the cell is 70mV less than that on the exterior. Under certain circumstances, the cell can redistribute charge so that the electric potential inside is 40 mV greater than that outside. Assuming the membrane is 12 nm thick and that the net electric field inside it is uniform, how does that field change in the transition from having an interior that is 70...
Ion channels that switch open and close as the potential difference across the cell membrane changes...
Ion channels that switch open and close as the potential difference across the cell membrane changes are an essential component of the cell membrane. Most such channels contain a molecular ion with a significant electrical charge at their core. Suppose a protein contains a molecular ion with a charge of -12e and that this protein is embedded in a cell membrane that has a thickness of 9 nm. What are the magnitude and direction of electric force on the ion...

a. Determine the average magnitude of the E⃗ field across a body cell membrane. A 0.070-V potential difference exists from one side to the other and the membrane is 7.4 ×10−9 m thick. Assume that the dielectric constant is 1.0 (it is actually somewhat larger). b. Determine the magnitude of the electrical force on a sodium ion (charge +e) in the membrane.

A)Determine the average magnitude of the E⃗ field across a body cell membrane. A 0.050-V potential difference exists from one side to the other and the membrane is 7.1 ×10−9 m thick. Assume that the dielectric constant is 1.0 (it is actually somewhat larger). The answer is not 7.0x10^-12 or 7 B) Determine the magnitude of the electrical force on a sodium ion (charge +e) in the membrane.

The membrane of
the axon of a nerve cell is a thin cylindrical shell of radius r-
10 m, length L 0.48 m, and thickness d 108 m. The membrane has a
positive charge on one side and a negative charge on the other, and
acts as a parallel plate capacitor of area A 2arL and separation d.
Its dielectric constant is about 7.

Many cells in the human body maintain an electric potential difference across their cellular membranes, typically through the use ion-specific pumps and channels that generate an excess of negative charges on the inside of the cellular membrane and an excess of positive charges on the outside. Let us estimate the total energy stored in the human body by this type of charge separation. Part a Different cells can have vastly different cell sizes; but as an approximation, let us assume...
