Why are potential differences equal across two capacitors in …
In a parallel combination of capacitors potential difference across each capacitor is same but each capacitor will store different charge. Why is this true? In a lumped circuit model, any two devices in parallel must have the same potential across them. This is because of Kirchoff''s voltage law (KVL) which says that the net potential …

When a free positive charge (q) is accelerated by an electric field, such as shown in Figure (PageIndex{1}), it is given kinetic energy. The process is analogous to an object being accelerated by a gravitational field. It is as if the charge is going down an electrical hill where its electric potential energy is converted to kinetic energy.
