Question:

A parallel-plate capacitor is made from two aluminum-foil sheets, each 5.7 wide and 5.3 longBetween the sh?

A parallel-plate capacitor is made from two aluminum-foil sheets, each 5.7cm wide and 5.3m longBetween the sheets is a Teflon strip of the same width and length that is 2.9×10^?2 mm thick.What is the capacitance of this capacitor? (The dielectric constant of Teflon is 2.1.)

Answer:

Capacitance k x ε0 x area / separation k teflon 2.1 ε0 8.854 10^-12 F/m area 0.057 5.3 0.3021 m2 separation 2.9 10^-5m C 2.1 8.854 10^-12 0.3021 / 2.9 10^-5 0.19369 10^-6 F 0.19369?F hyperphysics.phy-astr.gsu.edu/hbaGoodbye
