C = (E. * A) / (d) With dielectric C = (E. * A * k) / (d)

How do I find the area?

Yes, exactly. And since the width is known, the rest is easy

What do you think the value of d is? What must determine that value in the problem setup?

d is thickness of the paper X thickness of aluminum foil ?

And remember to keep in mind how many layers of paper are being called for here.

Yes. d is is (thickness of the paper X thickness of aluminum foil) / 4. Why have 2 thickness of the paper and 2 thickness of aluminum. Correct ?

No, there is a reason the problem does not specify the thickness of the foil.

I do not understand what is d in formula.

C = (E * x * y * k)/d

C * d = E * x * y * k

x = (C * d) / (E * y * k)

x = 1,036x10^{-5}m

It is correct ?

How so? Why do I have two sheets the distance is 50x10^{-6} and not 25x10^{-6} ?

To be clear, if the problem gives the total thickness of the two sheets of paper, your answer is correct; if it gives only the thickness of one you obviously must multiply by 2.

Yes thank you. If possible, I am very grateful if you help me in other problems. Thanks
