The next five questions use this description.
Dry air is a pretty decent insulator; it has a very high resistivity of 3 × 10³ Q · m . Consider a
capacitor that has square plates 15 cm on a side, separated by 0.8 mm of dry air. The capacitor is
charged such that it has a potential of 320 V between the plates.
First, what is the resistance of the volume of air between the plates in G2 (to 3 significant digits)?
