Answer to Question #312061 in Physics for Bibs

Question #312061

A capacitor is constructed from two conductive metal plates 30cm x 50cm

which are spaced 6mm apart from each other, and uses dry air as its only

dielectric material. Calculate the capacitance of the capacitor. (0.221nF).

Expert's answer

The capacitance of the parallel plates capacitor

C=\frac{\epsilon_0A}{d}

C=\frac{8.85*10^{-12}*0.3*0.5}{0.006}=2.21*10^{-10}\:\rm F=0.221\: n F
