Capacitor problem ! (Advanced)

    capacitor problem!!!!!! (Advanced)

    1. The problem statement, all variables and given/known data

    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! :smile:

    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.
