Capacitor in Electronics – What It Is and What It Does

This stored energy is released when needed, making capacitors essential components in various electronic circuits. How a Capacitor Works. When a capacitor is connected to a power source, electrons accumulate at one of the conductors (the negative plate), while electrons are removed from the other conductor (the positive plate). This creates a potential
