what are the charge densities of different cell membranes?

Question

lipid bilayer of all biological membranes is acting as a capacitor. i want to know the charge density of muscle,epithelial,neuron,endo peri &myocardium cells

Answer 1

Any substance that has both conductive and insulating properties can technically be a capacitor. So yes a cell has capacitance.

As far as charge density from a cell this is dependant on a number of parameters. Charge applied as the prime example, remember a drained capacitor has a charge density of zero.

Also the capacitance of tissues like you are referring to must fluctuate based on things like the concentration and types of ions inside the cells. Hydration within the cell should also be a factor. And then of course you need to look at the insulator, what are the types and concentrations of lipids.

I am not sure you can pinpoint a specific and verifiable a charge density for tissue.
