Every electronic devices contains transistors.A telephone consists of transistors.
Telephones'
Telephones were invented in 1876. No major milestone in telephones happened in 2000.
Power transistors are transistors that are used in high-power amplifiers and power supplies.
Transistors are made out of semiconductors, yes.
Every single country on earth has telephones.
5,4546,3545.3 telephones

The primary reason that NPN transistors are used more often than PNP transistors is that they usually operate faster (at higher frequencies) because the mobility of the current carriers in NPN transistors (electrons) is much higher than that of the current carriers in PNP transistors (holes).
