Capacitor

: 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

 

 

 

Equtions:

C=q/vab   
; 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
distance

The general equation for capacity that connected in  series; 1/Cequvelant=

 

For two capacitors C1,C2 connected  in series we have
Cequvelant= c1*c2/c1+c2   

    The general equation for
capacity that connected

        In parallel; cequvelant=

                  C equvelant= c1+c2+c3+….

Total work done

U=w=0.5q^2/c=0.5cv^2=0.5qv

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
