Difference Between Earth and Neutral
Neutral carries electric current while the earth has zero current flow through it except at disconnections or insulation failures. A neutral wire is connected directly to the main power wiring and not to the appliance. It is connected through a neutral line. Read More: Difference between Earth and Neutral Important Questions
Capacitor in Electronics
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.

X and Y Safety Capacitor Applications Explained | doEEEt
Their main difference is in the level of safety they provide. X capacitors are required for connections between mains or neutral. Y capacitors are required whenever there is a connection to grounded nodes. Due to the fact that equipment cases are usually grounded, Y caps require higher safety to avoid risks of electrical shocks to users.

4.1 Capacitors and Capacitance
The SI unit of capacitance is the farad (), named after Michael Faraday (1791–1867). Since capacitance is the charge per unit voltage, one farad is one coulomb per one volt, or . By definition, a capacitor is able to store of charge (a very large amount of charge) when the potential difference between its plates is only .One farad is therefore a very large capacitance.
