A parallel plate capacitor is required to be designed using polyethylene (PE) as the filler between the plates with a dielectric constant of 2.25. The capacitor is constructed with circular plates of radius 27mm. Taking the permittivity of a vacuum (0) to be 8.851012Fm1 and to be 3.142 : Calculate the gap required between the plates to give the component a capacitance of 43pF to one decimal place. l=mm
