30. The space between the plates of a plane capacitor has a volume V = 375 cm3, and filled with hydrogen, which is partly ionized. The area of the capacitor plates S = 250 cm2. At what voltage U between the plates of the capacitor current I, flowing through the capacitor reaches 2 mA, if the density n ions of both signs in the gas is equal to 5,3 • 107 cm-3? Take ion mobility b + = 5,4 • 10-4 m2 / (V • a), b- = 7,4 • 10-4 m2 / (V • s).
