The potential difference between the disks:
Area o the capacitor is expressed as:
A = πr2
r = d/2 = 4.8/2 = 2.4 cm
Two 4.8 cm diameter metal disks are separated by a 0.19 mm thick piece of paper. (Dielectric constant for paper is called kpaper = 3.7, its dielectric strength is 16x106 V/m .)
a) What is the capacitance?
b) What is the maximum potential difference between the disks?
