When a capacitor is connected to a battery, the charge is developed on each side of the capacitor. Also, there will be a flow of current in the circuit for some time, and then it decreases to zero. Where is energy stored in the capacitor? The energy is stored in the space that is available in the capacitor plates.
In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. If you have read How Batteries Work, then you know that a battery has two terminals.
Today, designers may choose ceramics or plastics as their nonconductors. A battery can store thousands of times more energy than a capacitor having the same volume. Batteries also can supply that energy in a steady, dependable stream. But sometimes they can’t provide energy as quickly as it is needed. Take, for example, the flashbulb in a camera.
To be sure, the battery puts out energy QV b in the process of charging the capacitor to equilibrium at battery voltage V b. But half of that energy is dissipated in heat in the resistance of the charging pathway, and only QV b /2 is finally stored on the capacitor at equilibrium.
The voltage on the capacitor is proportional to the charge Storing energy on the capacitor involves doing work to transport charge from one plate of the capacitor to the other against the electrical forces. As the charge builds up in the charging process, each successive element of charge dq requires more work to force it onto the positive plate.
Summary of the answer: We can say that the energy of the capacitor is lower because most of the time, the voltage of the capacitor is lower than the battery (so, the upper left part of the graph is missing in the case of the Capacitor which is present in the Battery). But the question is, where is the rest half?

Energy is transferred from the battery to the capacitor. Work is defined as a transfer of energy. Therefore, the battery does work on the capacitor.
The difference between a capacitor and a battery is that a capacitor can dump its entire charge in a tiny fraction of a second, where a battery would take minutes to completely discharge. That''s …
