In 1883, Thomas Alva Edison experimented with electric bulbs and discovered that electricity could pass through a vacuum between two metal conductors. In 1904, John Fleming developed the first electronic device, the diode valve, using this sensation known as the Edison effect. A vacuum diode has two electrodes, a cathode and an anode. They are mounted on an airtight glass or metal shield. When the cathode obtains heat directly or indirectly, it emits electrons. These electrons move through the vacuum to the positive terminal using positive energy. The innovation of controlling the flow of electricity from the cathode to the anode through a frame in the path of electrons is an insurrection. Before electronics were used to control the flow of electrons using such vacuum tubes. Vacuum tubes are known as a diode, triode, pentode, and diode depending on the number of electrodes used in them. With the invention of semiconductors, transistors took the place of vacuum tubes. Just as the Industrial Revolution led to the industrial age, the improvement of electronics led the modern world to the electronic age. Electronics is effective in all areas of communication, transportation, industry, agriculture, research, security, medicine and education.
