$SOLVED: Air isn't a perfect electric insulator, but it does have a veryhigh resistivity. Dry air has a resistivity of approximately 3×1013Ω⋅ m. Assume we have a capacitor with square plates 10 cm on aside separated by 1.0 mm of dry air. Assuming that the air betweenthe capacitor's plates can be treated like any other resistor, findits resistance value. Assuming that the air between the capacitor'splates can be treated like any other resistor, find its resistancevalue. What fraction of its initia$

$Air isn't a perfect electric insulator, but it has a very high resistivity. Dry air has a resistivity of approximately 3 ×10^13 Ω·m . A capacitor has square plates 10 cm on a side separated by 1.2 mm of dry air. If the capacitor is charged to 250 V, what fraction of the charge will flow across the air gap in 1 minute? Make the approximation that the potential difference doesn't change as the charge flows. | Numerade$

SOLVED: Though air's resistivity is very large, 3 Ã— 10^13 â„¦ Â· m, it isn't a perfect electric insulator. This means that the charges on a capacitor can "leak" from one plate to another slowly, causing the capacitor to discharge.(a.) Assume that the air between the plates obeys Ohm's law and treat the discharging capacitor as an RC circuit. Show that the time constant for a parallel-plate capacitor is independent of its geometry and therefore all air-filled capacitors take the same amount of t
