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.
Capacitance Capacitance is a capacitor''s ability for storing an electric charge per unit of voltage across its plates. The formula for capacitance is: 𝐶=𝑄 / 𝑉 where: 𝐶 is the capacitance in farads (F), 𝑄 is the charge in coulombs (C), 𝑉 is the voltage in volts (V).

When a capacitor is connected to a voltage source, like a power supply or battery, it causes a voltage difference between the plates, creating an electrical field. How does this happen? Electrons in the conductor connected to the negative terminal of the voltage source are repelled and flow onto one of the conductive plates, giving it a negative charge.
