Why Does Charging a Capacitor Result in Half the Energy Loss?

The integral or the sum of all the little Q x V steps is the area under the triangular graph. How does a capacitor store energy? When a capacitor is connected to a power source, such as a battery, the plates become charged with opposite charges. This creates an electric field between the plates, which stores the energy.

Batteries are like capacitors? : r/ElectricalEngineering

Batteries aren''t really like capacitors at all aside from the fact that they can store energy. Capacitors are not used for energy storage they same way that batteries are (aside from super capacitors maybe), instead they can be thought of as buckets that can store small amounts (compared to a battery) of energy to supply extra current when switching on a chip occurs (i.e
