Problem: A parallel-plate capacitor is made from two aluminum-foil sheets, each 6.7cm wide and 5.9m long. Between the sheets is a Teflon strip of the same width and length that is 3.5 x 10-2 mm thick. The dielectric constant of Teflon is 2.1.
Part A: What is the capacitance of this capacitor?
I need the answer and steps thanks!
