Here's a simple one:
Mainly there are two types of transistors. They are BJT (Bipolar Junction Transistors) and FET(Field Effect Transisters). In BJT, there are two types called PNP and NPN. Actually NPN means a BJT transister.
The two main types of transistors are bipolar junction transistors (BJTs) and field-effect transistors (FETs). BJTs operate by controlling the flow of current via two types - NPN and PNP. FETs control current flow using an electrical field, with types including MOSFETs and JFETs.
Similar to a 2N3906 PNP transistor
it doesn't have to be. depends on design of amplifier using transistor.

BT169 is neither an NPN nor a PNP transistor. BT169 is a thyristor, otherwise known as a silicon controlled rectifier.
A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.
The PNP transistors conducts when there is no signal at base (0V or grounded), when base current is increased the conduction of PNP transistor decreases.
same as you would using an NPN, except the supply voltages are reversed

To know if a transistor is PNP or an NPN,the following should be verified:For a PNP transistor, the base-collector junction is forward biased while the base-emitter junction is reversed biased.For an NPN transistor, the base-emitter junction is forward biased while the base -collector junction is reversed biased.
