One of the most common users of the capacitor is flash camera
: it is a device that has the ability
to store potential energy and electric charge by two conductors has the same charge but opposite sign and
charge will transform from the positive plat to the negative
During this process work must occur to transfer the charges through
the potential difference between the conductor
The symbols of the capacitor in electric circle
; c is a capacitance , q is a charge, vab is a volte between a and b
The units of capacitance is F (farad)
Also we can find a capacitance by C=£0A/d
£0 is the permittivity in space and
has value 8.85×10^-12, A is area , d is the
The general equation for capacity that connected in series; 1/Cequvelant=
For two capacitors C1,C2 connected in series we have
The general equation for
capacity that connected
In parallel; cequvelant=
C equvelant= c1+c2+c3+….
Total work done
Energy density u= 0.5 £o E^2
The formula for capacitance of parallel plat capacitor filled with
dielectric material is
C=kC0 =k£0A/d; C0 is capacitor without dielectric
£0 is permittivity in free space
are Generally superior to other species and therefore can be used in wide
ranges of application.
