In a discharge tube when `200` volt potential difference is applied `6.25xx10^(18)` electrons move from cathode to anode and `3.125xx10^(18)` singly charged positive ions move from anode to cathode in one second. Then the power of tube is:

Two electrodes are maintained at a potential difference of 100V. An electron moving from cathode to anode gains kinetic energy of :

In a discharge tube, 6 xx 10^18 electrons move to the left and 4 xx 10^18 protons move to the right past a cross-section in every second. Find the magnitude and the direction of current.

In an electrolyte 3.2 xx 10^(18) bivalent positive ions drift to the right per second while 3.6 xx 10^(18) monovalent negative ions drift to the left per second. Then the current is

In an electrolyte 3.2 xx 10^(18) bivalent positive ions drift to the right per second while 3.6 xx 10^(18) monovalent negaitve ions drift to the per second. Then the current is

A current is established in a gas discharge tube where a sufficiently high potential difference is applied across the two electrodes in the tube. The gas ionises , electrons move toward positive terminal and positive ions toward the negative. What are the magnitude and sense of the current in a hydrogen discharge tube in which 3.1 xx 10^18 electrons and 1.1 xx 10^18 protons move past a X-sectional area of the tube each second ?
