Wdwd (CC BY 3.0). The high input impedance has another effect less coupled to small signal work. Where a bipolar transistor requires significant base current to turn itself on, the corresponding ...

Transistors are used in a wide variety of applications. They can act as amplifiers, taking a small input signal and making it larger. They can also be used as switches, turning an electrical signal on ...

This germanium had an excess of electrons, but when an electric signal ... Brattain's transistor, current flowed towards the second gold contact. Think about what that means. A small current ...
