The result is a current of electrons flowing from filament to plate.

The simplest vacuum tubes resemble incandescent light bulbs in that they have a filament sealed in a glass envelope which has been evacuated of all air.When hot, the filament releases electrons into the vacuum: a process called thermionic emission.The electrodes are attached to leads which pass through the envelope via an air tight seal.On most tubes, the leads are designed to plug into a tube socket for easy replacement.Vacuum tubes, or thermionic valves, are arrangements of electrodes in a vacuum within an insulating, temperature-resistant envelope.

Although the envelope was classically glass, power tubes often use ceramic and metal.
