How does charge gather on both plates of the capacitor? In my textbook, it states that when a parallel-plate capacitor is connected to a battery, charge will flow from the battery onto both plates. How is this possible since current only flows from one end of the battery.
In each plate of the capacitor, there are many negative and positive charges, but the number of negative charges balances the number of positive charges, so that there is no net charge, and therefore no electric field between the plates.
When capacitors are used in circuits, the assumption is often made that the plates of the capacitors have equal and opposite charges. I was wondering why this is the case. I have done some research. One source, The Feynman Lectures on Physics (Vol. 2) explains ( Ch. 22 ): "We assume that the plates and the wires are perfect conductors.
During the charging process, the battery does work to remove charges from one plate and deposit them onto the other. Figure 5.4.1 Work is done by an external agent in bringing +dq from the negative plate and depositing the charge on the positive plate. Let the capacitor be initially uncharged.
Due to the attraction charges are in a way trapped within the plates of the capacitor. We know that we can give a certain amount of charge to a plate. If we supply more charge, the potential increases and it could lead to a leakage in the charge.
For 2 capacitors in series, ideally the charge on the "inner" plates would be 0. Not the answer you're looking for? Browse other questions tagged or ask your own question.
