Transistors are electronic components for signal control (current or voltage) between two jacks, depending on the signal applied to the other two jacks. As they only have three connections, one of them is common to the input and exit signals. This proportionality between the obtained signal and the given one is called Gain.
There are many types of transistors
based on their gain, polarity in their jacks, maximum currents, voltages of work, the encapsulation type, size, etc.
