define capacitor and it's all types and what is the use of it in circuit no chapachapi Haa abhi bol rhi hu........
Answers
define :
The ability of conductor to store an electric charge and electric potential energy is called capacitance of capacitor
types:
1)parallel plate capacitors
-it consist of two parallel plates conductors separated by distance having (k) dielectric constant
-those conductors having negative charge or inner side or at outer side
2)spherical capacitor
-spherical capacitor consist of two concentric sphere having radii (a) and (b)
-the outer surface of inner sphere is positive charged and outer sphere capacitor inner side part having negative charge
-outer surface of outer sphere is earthed
-a medium of permitivity is present in between two spheres
3)cylindrical capacitor
-cylindrical capacitor consist of two co-axial cylinder of radius (a) and (b) respectively
-outer surface of inner cylinder is positive charged
-inner surface of outer cylinder is negative charged
-medium of permitivity between two cylinder (r)
role of capacitor in circuit :
to store the electric charge between circuit
