How Does Voltage Affect Charge in Biological Capacitors?

[Oscar6330]

capacitor problem! (Advanced)

Homework Statement

I am simulating a Biological system. For ease just consider it as a parallel plate capacitor. Now the simulation software takes the value of charge Q, but not the value of V. Now as C=Q/V, can we say that the charge Q of a parallel plate capacitor remains constant and V (say we increase from 5-8 volts) has no effect on Q of the capacitor.

Hi Oscar6330!

Perhaps I'm misunderstanding the biology, but the whole point of a capacitor is that when you increase the voltage, you increase the build-up of charge (until the capacitor breaks down by a spark jumping across it).

Hey thanks for the reply. Hence this means that if I put the max theoratical Q value, I will be able to do it.
