473 Capacitor Working Principle
The working principle of a 473 capacitor (47,000 pF or 47 nF) is based on the ability of two conductive plates to store electrical energy in an electric field, separated by a dielectric material. Here’s how it works:
Energy Storage: When a voltage is applied across the capacitor’s terminals, electrons accumulate on one plate, creating a negative charge. Simultaneously, the other plate loses electrons, creating a positive charge. This creates an electric field between the plates.
Capacitance: The amount of charge a capacitor can store depends on the surface area of the plates, the distance between them, and the dielectric constant of the material between the plates.
Charge-Discharge Cycle: The capacitor charges when connected to a power source and discharges when the circuit demands energy, allowing it to act as a temporary energy reservoir.
AC/DC Response: Capacitors block direct current (DC) but allow alternating current (AC) to pass, making them essential for filtering, coupling, and bypassing applications.
