![]() one of the three terminals of a transistor is used for input and one for output, while the third one is used as a ground and which is common for both input terminal and output terminals) As there are just 3 terminals in a transistor, therefore it should be kept in mind that one of its terminals (called the ground terminal) is common with its input and output. ![]() (or amplifies it), thus an amplified electrical signal can be received between the other two output terminals. Its biggest advantage is that if a weak electrical signal is provided between its two input terminals, it magnifies the power of this weak signal. The detail is as belowīasically, a transistor can be utilized as an amplifier or as an amplifying unit. Transistor as an Amplifier:- Bipolar junction transistors are mostly used for amplification and switching purposes. Bipolar Junction Transistor (BJT) As A Switch.Collector Curves and Operation Regions of Transistor. ![]() Comparison of CB, CE, and CC Amplifier Circuits :.
