Source sentences:
text: In vacuum tubes (including cathode ray tubes) it is the negative terminal where electrons enter the device from the external circuit and proceed into the tube's near-vacuum, constituting a positive current flowing out of the device.
text: The electrons enter the device through the cathode and exit the device through the anode.
text: CCD means cathode current departs: a positive current always departs the device; electrons carry a negative charge, so a positive conventional current is the same as electrons entering the device.
text: Consequently, electrons leave the device through the anode and enter the device through the cathode.
text: Similarly, in a vacuum tube only one electrode can emit electrons into the evacuated tube due to being heated by a filament, so electrons can only enter the device from the external circuit through the heated electrode.
text: The electrons enter the device through the cathode and exit the device through the anode.
