Chapter 22, Problem 47GP
Air isn’t a perfect electric insulator, but it has a very high resistivity. Dry air has a resistivity of approximately 3 × 1013 Ω · m. A capacitor has square plates 10 cm on a side separated by 1.2 mm of dry air. If the capacitor is charged to 250 V, what fraction of the charge will flow across the air gap in 1 minute? Make the approximation that the potential difference doesn’t change as the charge flows.
