• S8050 NPN Transistor for Low Signal Applications

  by Yang crystal March 22, 2023
  The S8050 is an NPN transistor with low voltage and high current that can be used to create Class B push-pull amplifiers. In the bipolar junction transistor S8050, holes are the minor carriers while electrons are the major ones. S8050 is primarily used as an amplifier for boosting low signals, such ...

• The Best Explain of Nitrous oxide (N2O)

  by Yang crystal October 14, 2022
  Nitrous oxide (N2O) is called “laughing gas” because it has a euphoric effect when inhaled. It has a mildly sweet odor and taste. N2O was first synthesized by J. Priestley in 1772. In 1800, H. Davy showed that it is an analgesic; its use as a recreational drug began around the same ...
