The discussion centers on calculating the plate area of a parallel-plate capacitor that matches the capacitance of a spherical capacitor with a capacitance of 12.4 pF and a plate separation of 0.012 m. The formula used is C = (ε * A) / d, where ε is the permittivity of free space (8.85 x 10^-12 F/m). The correct calculation yields an area A of 0.0168 m², which converts to 168 cm², not 1.68 cm², highlighting the importance of accurate unit conversion in capacitor calculations.
PREREQUISITESStudents studying physics, particularly those focusing on electromagnetism and capacitor theory, as well as educators looking for examples of common calculation errors in capacitor problems.
juggalomike said:so A=.0168m^2=1.68cm^2, which is incorrect?
collinsmark said:0.0168 m2 ≠ 1.68 cm2.
1 square meter does not contain 100 square centimeters. Rather it contains (100 [cm]) X (100 [cm]) = 10000 square centimeters.
