A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.
The charge q on a capacitor''s plate is proportional to the potential difference V across the capacitor. We express this relationship with where C is a proportionality constant known as the capacitance. C is measured in the unit of the farad, F, (1 farad = 1 coulomb/volt).

However, the real-time voltage across the capacitor follows a curve that gradually slows down and decreases in curvature. The voltage across the capacitor doesn''t instantly become equal to the power source like the resistor does. Instead, it gradually increases over time, effectively preventing a sudden voltage change across the capacitor.
