This opened up the possibilities for the use of electricity as a power supply and paved the way for the age of electronics.
Detailed explanation-3: -John Ambrose Fleming was an electronics pioneer who invented the oscillation valve, or vacuum tube, a device that would help make radios, televisions, telephones and even early electronic computers possible.
Detailed explanation-4: -He is best remembered as the inventor of the two-electrode radio rectifier, which he called the thermionic valve; it is also known as the vacuum diode, kenotron, thermionic tube, and Fleming valve.
