What does the net charge on a capacitor depend on? | Quizlet
The charge on one of the plates is calculated as: Q = C V, (1) Q = CV tag{1} , Q = C V, (1) and is usually called the charge of the capacitor. However, that is the amount of the charge for each of the plates and not the net charge of the entire capacitor.
