To get an idea how big a farad is, suppose you want to make a 1-f air-filled parallel-plate capacitor for a circuit you are building. to make it a reasonable size, suppose you limit the plate area to what would the gap have to be between the plates? is this practically achievable?

Solution:

As per the question:

Capacitance, C = 1 F

Area of the plate of the capacitor, A =

Now,

To calculate the distance, D between the plates of a parallel plate capacitor:

Thus

where

= permittivity of free space

Now,

This distance much smaller and is practically not possible

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
