Symbol of NPN
The Symbol for NPN can be given as
NPN Transistor
An NPN Transistor is a Negative-Positive-Negative transistor that has a significant and varied impact on electronic circuits. The NPN transistor is made up of three semiconductor layers that are arranged in a particular way. One of the layers is of the negative (N) type and is sandwiched between two of the positive (P) types.
Its name is derived from this distinctive arrangement: NPN. Electrons flow from the N-type region through the P-type region when a voltage is applied across the transistor’s terminals, resulting in controlled conductivity and allowing the transistor to act as an amplifier or switch.
