2. CAPACITOR
A Capacitor is a passive component that has the ability
to store the energy in the form of potential difference
between its plates.
A non-conducting region is present between these two
plates which is called as dielectric. This dielectric can
be vacuum, air, mica, paper, ceramic, aluminum etc.
The standard units for capacitance is Farads.
3. CAPACITANCE OF CAPACITOR
Capacitance is defined as being that a capacitor has the
capacitance of One Farad when a charge of One
Coulomb is stored on the plates by a voltage of One volt.
4. The generalized equation for the
capacitance of a parallel plate capacitor
is given
as: C = ε(A/d) where ε represents the
absolute permittivity of the dielectric
material being used. The permittivity of
a vacuum, εo also known as the
“permittivity of free space” has the
value of the constant 8.84 x 10-12
Farads
per metre.
