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.
