Energy Storage Elements: Capacitors and Inductors To this point in our study of electronic circuits, time has not been important. The analysis and designs we have performed so far have been static, and all circuit responses at a given time have depended only on the circuit inputs at that time. In this chapter, we shall introduce two important passive circuit elements: the
Energy Storage in Capacitors • Recall in a parallel plate capacitor, a surface charge distribution 𝜌𝑠+( ) is created on one conductor, while charge distribution 𝜌𝑠−( ) is created on the other. Q: How much energy is stored by these charges?

This is NOT like a battery where the amount of charge GENERATED is independent of voltage. You can only take out of a capacitor what you put into it. is called the CAPACITANCE of the device.
Capacitors as an energy storage device: It takes work (i.e. energy) to charge up a capacitor from zero charge to q(zero potential to V).

Capacitors store electric energy when they are connected to a battery or some other charging circuit. They are commonly placed in electronic components and are used to maintain a power supply while the device is unplugged and without a battery for a short time.
Energy Storage: Capacitors can be used to store energy in systems that require a temporary power source, such as uninterruptible power supplies (UPS) or battery backup systems. Power Factor Correction: Capacitors are employed in power factor correction circuits to improve the efficiency of electrical systems by reducing the reactive power drawn from the

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.
Capacitors are vital for energy storage in electronic circuits, with their capacity to store charge being dependent on the physical characteristics of the plates and the dielectric material. The quality of the dielectric is a significant factor in the capacitor's ability to store and retain energy.
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 permittivity is a measure of how much electric field the dielectric can sustain, which affects the capacitor's ability to store charge. The dielectric material is crucial in determining the efficiency and stability of a capacitor's energy storage.
As we discussed, the devices have constitutive relations that are closely analogous to those of sources. Capacitors source a voltage Q/C and inductors source a current Λ/L, but this simple picture isn’t quite suficient. The issue is that Q and change depending on Λ the current and voltage across the device.
Capacitors are essential electronic components that store and release electrical energy in a circuit. They consist of two conductive plates, known as electrodes, separated by an insulating material called the dielectric.
