with the help of an example show that farad is a very large unit of capacitance
Answers
Farad (F) is the SI unit of capacitance (C), a physical
quantity commonly encountered in electrostatics. It is a measure of the
capacity of a capacitor to store energy in itself.
The formula for capacitance is:
C = A e / d
Where C = Capacitance
A = Area of capacitor plate
e = Permittivity Constant
d = Distance between plates
Assuming that we want a capacitance of 1 Farad with a distance of 1 cm in between both plates, the area of both the plates will be nearly 12 x 10^8 square metres. As such dimensions are not possible, we conclude that the Farad is a very large unit of capacitance.
Answer:
Farad is the SI unit of capacitance. By definition, a capacitor of one farad produces a potential difference of one volt between its plates when it stores an electric charge of one coulomb. One coulomb in terms of charge is an extremely huge amount of charge as it is produced by 6.25 x 1018 electrons.
