Homework Statement
A parallel-plate capacitor is made from two aluminum-foil sheets, each 3.80cm wide and 15.0m long. Between the sheets is a mica strip of the same width and length that is 0.0225mm thick.
What is the maximum charge that can be stored in this capacitor? (The dielectric constant of mica is 5.4, and its dielectric strength is 1.00*10^8 V/m).
Homework Equations
C = k(Eo*A)/d
V = Ed = (Eo/K)*d
The Attempt at a Solution
I'm not sure how to start this question. I know that I would need to find A through all the dimernsions givens, but the mica strip between the sheets is confusing me, I'm not sure how to find A. I'm really confused and would appreciate it if someone can give me some guidance. Thanks.
