Task 30235.
To the electrodes of the discharge tube consisting of hydrogen, a potential difference U = 10 V. The distance d between electrodes is 25 cm. Ionizer creates a volume V = 1 cm ^ 3 hydrogen n = 10 ^ 7 pairs of ions per second. Find the current density j in the tube. Define also which part of the current created by the movement of the positive ions.
Detailed solution shorthand terms, formulas and laws used in the decision, the withdrawal of the calculation formula and the response.
