Question a parallel-plate capacitor is made from two, Ask an Expert

Academics

Question: A parallel-plate capacitor is made from two aluminum-foil sheets, each 7.3cm wide and 5.0m long. Between the sheets is a Teflon strip of the same width and length that is 4.2×102mm thick.

Part A: What is the capacitance of this capacitor? (The dielectric constant of Teflon is 2.1.)

Please show your work to determine the capacitance of capacitor, so I can understand process. Thank you!
