Cathode electronics Britannica
Cathodes are induced to emit electrons by several mechanisms: Thermionic emission: The cathode can be heated. The increased thermal motion of the metal atoms "knocks" electrons out of the surface, an effect called thermionic emission. This technique is used in most vacuum tubes. Ver mais A cathode is the electrode from which a conventional current leaves a polarized electrical device. This definition can be recalled by using the mnemonic CCD for Cathode Current Departs. A conventional current describes … Ver mais The word was coined in 1834 from the Greek κάθοδος (kathodos), 'descent' or 'way down', by William Whewell, who had been consulted by Michael Faraday over some new names needed to complete a paper on the recently discovered process of electrolysis. In … Ver mais Vacuum tubes In a vacuum tube or electronic vacuum system, the cathode is a metal surface which emits free electrons into the evacuated space. … Ver mais • The Cathode Ray Tube site • How to define anode and cathode Ver mais Conventional current flows from cathode to anode outside of the cell or device (with electrons moving in the opposite direction), regardless of the cell or device type and operating … Ver mais In chemistry, a cathode is the electrode of an electrochemical cell at which reduction occurs.
