Answer :


Q = 12μc =

V = 1200V

dielectric strength, b = 3 x 106V/m

Plate Area can be calculated as follows –

The separation between the plates of the capacitor is given by-

where v is the applied voltage and b is the dielectric strength

Now, the capacitance of the capacitor is given by

where Q is the charge stored and V is the voltage applied.

We know, capacitance c is given by-


A= Plate Area

d= separation between the plates,

0 = Permittivity of free space = 8.854 × 10-12 m-3 kg-1 s4 A2

Thus, the area of the plates is given by –

A= m2

=0.45 m2
