Energy stored in a capacitor is electrical potential energy, and it is thus related to the charge Q and voltage V on the capacitor. We must be careful when applying the equation for electrical potential energy ΔPE = q Δ V to a capacitor.

Capacitor charging and Energy storage

Electrical potential energy is supposedly stored because it takes work to move charge against the electric field (and in fact equal to the work if we set 0 potential energy to an uncharged state). As an analogy, I imagine a capacitor as a spring where "compressing the spring" means adding charge.

Energy Stored on a Capacitor

The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor.The voltage V is proportional to the amount of charge which is already on the capacitor.

Why is there an "electric" potential drop across the resistor?

An electric potential difference is created when two charges are separated. In a capacitor, there is a clear accumulation of opposite charges on the two separated plates, therefore work has to be done in moving an unit charge from one plate to another, against the electric field.. But, according to this answer, a potential difference is created in a resistor due

Capacitor

OverviewHistoryTheory of operationNon-ideal behaviorCapacitor typesCapacitor markingsApplicationsHazards and safety

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.

Why do we use "U" as the symbol for potential energy? :

Educated guess: V is used for an electric potential because of Volta. U is the letter most similar to V - there are lots of times when, if V is used as a variable for a concept, then U is a variable for a similar concept. So potential energy became U, because someone might have been trying to make a connection with potential voltage.

eli5: I understand how capacitors store electrical energy, but how do

Yes, the charges move around the circuit from one plate to the other, that''s how the current is generated. The charges *really* want to get to the other plate because of the voltage difference.
