NOTATION

: Electrical capacity is the ability of a conductor or capacitor to accumulate charge.
: Electric charge is a quantity that determines the participation of a body in electrical interaction.
: Electric voltage is the work done by the electric field when transferring a unit charge.
: Electric constant is a coefficient characterizing the electric field in a vacuum.
: Dielectric constant is a characteristic of the influence of the medium on the electric field.
: Area is the size of a surface or cross section.
: The distance between the plates is the gap between the plates of the capacitor.
: Electric field energy is the energy stored by an electric field or a capacitor.
: A period is the time of one complete repetition of a process.
: Inductance is the ability of a conductor to create a magnetic field when current passes.
