Contemporary Examples of filament
The B voltage gives the plate a positive charge to attract electrons from the filament.
When you connect the A battery, the filament of the tube is heated to release negatively charged electrons.
Electrons travel through the partial vacuum inside the tube, flowing from the filament to the positively charged plate.
Many tubes also have small structures, known as grids, between the filament and the plate.
