Transistors
N-P-N transistor
The switching time of NPN transistor is more as compared to PNP transistor because the majority charge carriers of NPN transistor are electrons. (The mobility of N type charge carriers (negative electrons) in silicon (Si) is two times more than the mobility of P type charge carriers (positive holes) in Si. Resulting in faster transistor operating speed)

If the base is at a higher voltage than emitter, current flows from collector to emitter.

If the base is at a lower voltage than emitter, current flows from emitter to collector.

As amplifiers they are being used in multiple oscillators, modulators, detectors and nearly in any circuit in order to perform a function. In digital circuits, transistors are used as switches.
