tunul electronic, deplasarea de sarcini electrice și definiția curentului electric

The accumulation of gas is cumulative for long time (the chamber is well sealed), even the current will be on micro ampere size.
For the CRT source, a circuit similar to that presented in fig 5., is used.
In order to have a clear result, the experiment longs 10 days and was repeated 4 times with 2 different CRT tubes (one color and another black and white).
After 10 days, no gas is released, for an electron charge displacement, at both electrodes, even the digital ammeter indicated 17,4 microA for color CRT and 11,1 micro A for black and white CRT.

By comparison two chemical batteries (1,5V) connected in series for 5 minutes, gave a current of 0,89 mA and in electrodes chamber both hydrogen and oxygen are produced as in fig. 4.

As is observed, at one electrode a double volume (hydrogen) is released, in comparison with the other electrode (oxygen).
