Vacuum Tube Function at Caitlin Shaeffer blog

Vacuum Tube Function. An electron tube has two or more electrodes separated either by vacuum (in a vacuum tube) or by ionized gas at low pressure (in a gas tube). This is called thermionic emission. The air inside the tubes is removed by a vacuum. A vacuum tube, also called a valve in british english, is an electronic device used in many older model radios, television sets, and amplifiers to control electric current flow. A vacuum tube is a hollow glass bulb, approximately cylindrical in shape, that contains a positive electrode and a negative. In 1904, english physicist john ambrose fleming took advantage of this effect to create the first vacuum tube device, which he called an oscillation valve. In this experiment, a metal plate was placed in. You heat up a metal, and the thermal energy knocks some electrons loose. The basic working principle of a vacuum tube is a phenomenon called thermionic emission. In a typical amplifier circuit, a small input signal is applied. The basic function of a vacuum tube is to amplify electronic signals. The vacuum tube is a direct result of thomas edison’s experiment with the incandescent lamp. The cathode is heated, as in a light bulb, so it will emit electrons.
