2. TYPES OF CIRCUIT ELEMENTS THAT STORE ENERGY

CAPACITORS

Capacitors are devices that store electrical energy temporarily through an electric field. These elements consist of two conductive plates separated by an insulating material known as a dielectric, which can be air, ceramic, plastic, or other substances. When a voltage is applied across the plates, an electric field forms, causing positive charge to accumulate on one plate and negative charge on the other. The primary characteristic of capacitors is their capacitance, measured in farads (F), which quantifies the ability to store charge at a given voltage.

The speed at which capacitors can charge and discharge makes them incredibly useful in various applications. For instance, in power supply smoothing, capacitors smooth out voltage fluctuations, ensuring that connected circuits receive a stable power supply. Additionally, in timing applications, they can create oscillations and delay functions essential for specific functions in digital circuits. This operational capability highlights their vital role in the stability and reliability of electronic devices.

INDUCTORS

Inductors store energy in a magnetic field when electric current passes through them. They consist of coils of wire, often wound around a magnetic core to enhance the magnetic field strength. The fundamental principle governing inductors is inductance, measured in henries (H), which defines their ability to store magnetic energy based on the amount of current flowing through and the characteristics of the coil.

Inductors perform oppositely to capacitors regarding energy release and storage. When the current through an inductor changes, the magnetic field collapses, inducing a voltage that opposes the change in current, according to Lenz’s Law. This feature makes inductors essential in applications like filtering, energy storage in switch-mode power supplies, and in radio frequency circuits for tuning and signal processing. The interaction between inductors and capacitors creates resonance, a phenomenon exploited in oscillator circuits and radio transmitters to generate specific frequencies.
