Aparallel-plate capacitor has a capacitance of 1.97 pf and a plate area of 5.86 cm2. what is the separation distance between the plates?

2.63 mm

Explanation:

The capacitance of a parallel-plate capacitor is given by

where

is the vacuum permettivity

A is the area of each plate of the capacitor

d is the separation between the two plates

In this problem, we know:

is the capacitance

is the area

Re-arranging the equation and substituting numbers, we can find the separation between the plates, d:
