The plates of a parallel-plate capacitor are made of circular discs of radii 5.0 cm each. If the separation between the plates is 1.0 mm, what is the capacitance?

Parallel plate capacitor: When two conducting plates are connected in parallel and separated by some distance then parallel plate capacitor will be formed.


Given:



Radius r= 5cm


Separation between the plates is


Formula used:


Capacitance is given by the formula



Where,


C is the capacitance of the capacitor


ε is the permittivity of free space =


A is the area of the circle m2


Because capacitor plates are made of circular discs)


d is the separation between the plates


Putting the values in the above relation, we get



Capacitance is of a circular disc parallel plate capacitor
