selenium rectifier मीनिंग इन हिंदी

उदाहरण वाक्य

1. In 1933 selenium rectifiers were invented.
2. Solid-state technology was in its infancy, represented by copper oxide and selenium rectifiers.
3. Selenium rectifiers were generally more efficient than metal-oxide types, and could handle higher voltages.
4. They were replaced in power supplies beginning in the 1940s by selenium rectifiers and then by semiconductor diodes by the 1960s.
5. The development of selenium rectifiers began during the early 1930s, and these replaced copper oxide rectifiers because they were more efficient.
6. Though once widely used, selenium rectifiers have mostly been replaced ( or are being replaced ) by silicon-based devices.
7. Zenith used a selenium rectifier of later versions of the T / O, replacing rectifier tubes used on the earlier models.
8. These selenium rectifiers were used ( and are still used ) to convert alternating current to direct current in electrical power applications.
9. Selenium rectifiers were once widely used as high-tension rectifiers in transformerless radio and TV sets, before cheaper silicon diodes became available.
10. The Harvard was a fixed bias amplifier, using a basic cathodyne phase inverter, but did include a selenium rectifier in the bias circuit.
